The spectra, spanning the energy range from 25 keV to 300 keV, were analyzed using a detector response matrix inversion technique that converts the spectra from counts/sec-sq cm-kev to photons/sec-sq cm-kev allowing direct comparison with theoretical models. The results indicate that the bulk of the Co-56 is mixed moderately through the inner regions of the SN envelope but they do not preclude the mixing of a small amount of the Co-56 further out into the envelope necessary to account for the observed Co-56 line fluxes. The effect of the ratio of Co-57 to Co-56 on the 11 Nov. 1988, continuum spectrum is discussed."> <base href="/"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="icon"

name="citation_abstract" content="SN1987A hard x ray continuum spectra obtained on 29 Oct. 1987, 9-10 Apr. 1988, and 11 Nov. 1988, from balloon flight measurements are presented. The spectra, spanning the energy range from 25 keV to 300 keV, were analyzed using a detector response matrix inversion technique that converts the spectra from counts/sec-sq cm-kev to photons/sec-sq cm-kev allowing direct comparison with theoretical models. The results indicate that the bulk of the Co-56 is mixed moderately through the inner regions of the SN envelope but they do not preclude the mixing of a small amount of the Co-56 further out into the envelope necessary to account for the observed Co-56 line fluxes. The effect of the ratio of Co-57 to Co-56 on the 11 Nov. 1988, continuum spectrum is discussed."><meta name="citation_author" content="Pendleton, Geoffrey N."><meta name="citation_author_institution" content="Alabama Univ.

class="mat-card-subtitle">SN1987A hard x ray continuum spectra obtained on 29 Oct. 1987, 9-10 Apr. 1988, and 11 Nov. 1988, from balloon flight measurements are presented. The spectra, spanning the energy range from 25 keV to 300 keV, were analyzed using a detector response matrix inversion technique that converts the spectra from counts/sec-sq cm-kev to photons/sec-sq cm-kev allowing direct comparison with theoretical models. The results indicate that the bulk of the Co-56 is mixed moderately through the inner regions of the SN envelope but they do not preclude the mixing of a small amount of the Co-56 further out into the envelope necessary to account for the observed Co-56 line fluxes. The effect of the ratio of Co-57 to Co-56 on the 11 Nov. 1988, continuum spectrum is discussed.</mat-card-subtitle><mat-card-content _ngcontent-sc170="" class="mat-card-content details-container"><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-33"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-34">Document ID</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-35"> 19940022186 </div></div><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-36"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-37">Acquisition Source</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-38"> Legacy CDMS </div></div><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row flex-layout-25"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-26">Document Type</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-27"> Other </div></div><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-39"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-40">Authors</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-41"><mat-chip-list _ngcontent-sc170="" class="mat-chip-list ng-star-inserted" id="mat-chip-list-1588844" tabindex="0" aria-required="false" aria-disabled="false" aria-invalid="false" aria-multiselectable="false" role="listbox" aria-orientation="horizontal"><div class="mat-chip-list-wrapper"><mat-chip _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="mat-chip mat-focus-indicator mat-primary mat-standard-chip _mat-animation-noopable flex-layout-42" tabindex="-1" role="option" aria-disabled="false"><div class="mat-chip-ripple flex-layout-43"></div> Pendleton, Geoffrey N. </mat-chip><span _ngcontent-sc170="" class="flex-layout-44"><em _ngcontent-sc170="" fxflex="" class="ng-star-inserted flex-layout-45">(Alabama Univ.

The spectra, spanning the energy range from 25 keV to 300 keV, were analyzed using a detector response matrix inversion technique that converts the spectra from counts/sec-sq cm-kev to photons/sec-sq cm-kev allowing direct comparison with theoretical models. The results indicate that the bulk of the Co-56 is mixed moderately through the inner regions of the SN envelope but they do not preclude the mixing of a small amount of the Co-56 further out into the envelope necessary to account for the observed Co-56 line fluxes. The effect of the ratio of Co-57 to Co-56 on the 11 Nov. 1988, continuum spectrum is discussed.&q;,&q;title&q;:&q;Balloon-borne measurements of the SN1987A hard x ray continuum&q;,&q;stiType&q;:&q;OTHER&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;submittedDate&q;:&q;2013-09-06T19:08:00.0000000+00:00&q;,&q;isLessonsLearned&q;:false,&q;authorAffiliations&q;:[{&q;sequence&q;:0,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Pendleton, Geoffrey N.&q;},&q;organization&q;:{&q;name&q;:&q;Alabama Univ.&q;,&q;location&q;:&q;Huntsville., United States&q;}},&q;id&q;:&q;a188682405134fe3a5e1a2835d3acb81&q;},{&q;sequence&q;:1,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Paciesas, William S.&q;},&q;organization&q;:{&q;name&q;:&q;Alabama Univ.&q;,&q;location&q;:&q;Huntsville., United States&q;}},&q;id&q;:&q;ad7f92f342104755839684ff6797f4ef&q;},{&q;sequence&q;:2,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Fishman, Gerald J.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;5b68347e02334913bfaea98a9e4680f7&q;},{&q;sequence&q;:3,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Meegan, Charles A.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;ccaa35af2af54ac68c51e3b5f71152df&q;},{&q;sequence&q;:4,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Wilson, Robert B.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;ce5df5849a1c458298c120b726fd87f0&q;}],&q;disseminated&q;:&q;METADATA_ONLY&q;,&q;stiTypeDetails&q;:&q;Other&q;,&q;technicalReviewType&q;:&q;TECHNICAL_REVIEW_TYPE_NONE&q;,&q;modified&q;:&q;2024-10-12T11:03:11.2623340+00:00&q;,&q;id&q;:19940022186,&q;publications&q;:[{&q;submissionId&q;:19940022186,&q;id&q;:&q;5bd11b8a44c24ac4a8a60fcdbc02610b&q;,&q;publicationName&q;:&q;Alabama Univ., BATSE Data Analysis&q;,&q;publicationDate&q;:&q;1994-02-15T00:00:00.0000000+00:00&q;}],&q;status&q;:&q;CURATED&q;,&q;related&q;:[{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940022182,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;BATSE Data Analysis&q;,&q;stiType&q;:&q;OTHER&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;status&q;:&q;CURATED&q;},{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940020866,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;National Aeronautics and Space Administration (NASA)/American Society for Engineering Education (ASEE) Summer Faculty Fellowship Program, 1993, volume 1&q;,&q;stiType&q;:&q;CONFERENCE_PROCEEDINGS&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;status&q;:&q;CURATED&q;},{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940020866,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;National Aeronautics and Space Administration (NASA)/American Society for Engineering Education (ASEE) Summer Faculty Fellowship Program, 1993, volume 1&q;,&q;stiType&q;:&q;CONFERENCE_PROCEEDINGS&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;accessionNumber&q;:&q;N94-25349 through N94-25366&q;,&q;status&q;:&q;CURATED&q;}],&q;downloads&q;:[],&q;downloadsAvailable&q;:false,&q;index&q;:&q;submissions-2024-11-21-05-09&q;},&q;G.json./api/citations/19940022186?&q;:{&q;body&q;:{&q;legacyMeta&q;:{&q;__type&q;:&q;LegacyMetaIndex, StrivesApi.ServiceModel&q;,&q;accessionNumber&q;:&q;94N26689&q;},&q;copyright&q;:{&q;disclosedInvention&q;:false,&q;thirdPartyPermissionsProduced&q;:false,&q;disclosedToPublic&q;:false,&q;submissionId&q;:19940022186,&q;containsThirdPartyMaterial&q;:false,&q;containsIndication&q;:false,&q;belongsToPublisher&q;:false,&q;id&q;:&q;cfed0b490e3d4d86a17598fd93341afa&q;,&q;publisherPermissionOrRightsToDistribute&q;:false,&q;determinationType&q;:&q;GOV_PUBLIC_USE_PERMITTED&q;,&q;thirdPartyContentCondition&q;:&q;NOT_SET&q;,&q;belongsToContractor&q;:false},&q;subjectCategories&q;:[&q;Space Radiation&q;],&q;exportControl&q;:{&q;isExportControl&q;:&q;NO&q;,&q;submissionId&q;:19940022186,&q;ear&q;:&q;NO&q;,&q;id&q;:&q;720c832c4f234006b9c05a5d35c286a6&q;,&q;itar&q;:&q;NO&q;},&q;created&q;:&q;2013-09-06T19:08:00.0000000+00:00&q;,&q;distributionDate&q;:&q;2019-01-24T00:00:00.0000000+00:00&q;,&q;center&q;:{&q;code&q;:&q;CDMS&q;,&q;name&q;:&q;Legacy CDMS&q;,&q;id&q;:&q;092d6e0881874968859b972d39a888dc&q;},&q;onlyAbstract&q;:false,&q;sensitiveInformation&q;:2,&q;abstract&q;:&q;SN1987A hard x ray continuum spectra obtained on 29 Oct. 1987, 9-10 Apr. 1988, and 11 Nov. 1988, from balloon flight measurements are presented.

The effect of the ratio of Co-57 to Co-56 on the 11 Nov. 1988, continuum spectrum is discussed.&q;,&q;title&q;:&q;Balloon-borne measurements of the SN1987A hard x ray continuum&q;,&q;stiType&q;:&q;OTHER&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;submittedDate&q;:&q;2013-09-06T19:08:00.0000000+00:00&q;,&q;isLessonsLearned&q;:false,&q;authorAffiliations&q;:[{&q;sequence&q;:0,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Pendleton, Geoffrey N.&q;},&q;organization&q;:{&q;name&q;:&q;Alabama Univ.&q;,&q;location&q;:&q;Huntsville., United States&q;}},&q;id&q;:&q;a188682405134fe3a5e1a2835d3acb81&q;},{&q;sequence&q;:1,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Paciesas, William S.&q;},&q;organization&q;:{&q;name&q;:&q;Alabama Univ.&q;,&q;location&q;:&q;Huntsville., United States&q;}},&q;id&q;:&q;ad7f92f342104755839684ff6797f4ef&q;},{&q;sequence&q;:2,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Fishman, Gerald J.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;5b68347e02334913bfaea98a9e4680f7&q;},{&q;sequence&q;:3,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Meegan, Charles A.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;ccaa35af2af54ac68c51e3b5f71152df&q;},{&q;sequence&q;:4,&q;submissionId&q;:19940022186,&q;meta&q;:{&q;author&q;:{&q;name&q;:&q;Wilson, Robert B.&q;},&q;organization&q;:{&q;name&q;:&q;NASA Marshall Space Flight Center&q;,&q;location&q;:&q;Huntsville, AL, United States&q;}},&q;id&q;:&q;ce5df5849a1c458298c120b726fd87f0&q;}],&q;disseminated&q;:&q;METADATA_ONLY&q;,&q;stiTypeDetails&q;:&q;Other&q;,&q;technicalReviewType&q;:&q;TECHNICAL_REVIEW_TYPE_NONE&q;,&q;modified&q;:&q;2024-10-12T11:03:11.2623340+00:00&q;,&q;id&q;:19940022186,&q;publications&q;:[{&q;submissionId&q;:19940022186,&q;id&q;:&q;5bd11b8a44c24ac4a8a60fcdbc02610b&q;,&q;publicationName&q;:&q;Alabama Univ., BATSE Data Analysis&q;,&q;publicationDate&q;:&q;1994-02-15T00:00:00.0000000+00:00&q;}],&q;status&q;:&q;CURATED&q;,&q;related&q;:[{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940022182,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;BATSE Data Analysis&q;,&q;stiType&q;:&q;OTHER&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;status&q;:&q;CURATED&q;},{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940020866,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;National Aeronautics and Space Administration (NASA)/American Society for Engineering Education (ASEE) Summer Faculty Fellowship Program, 1993, volume 1&q;,&q;stiType&q;:&q;CONFERENCE_PROCEEDINGS&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;status&q;:&q;CURATED&q;},{&q;disseminated&q;:&q;DOCUMENT_AND_METADATA&q;,&q;id&q;:19940020866,&q;type&q;:&q;ANALYTIC_PRIMARY&q;,&q;title&q;:&q;National Aeronautics and Space Administration (NASA)/American Society for Engineering Education (ASEE) Summer Faculty Fellowship Program, 1993, volume 1&q;,&q;stiType&q;:&q;CONFERENCE_PROCEEDINGS&q;,&q;distribution&q;:&q;PUBLIC&q;,&q;accessionNumber&q;:&q;N94-25349 through N94-25366&q;,&q;status&q;:&q;CURATED&q;}],&q;downloads&q;:[],&q;downloadsAvailable&q;:false,&q;index&q;:&q;submissions-2024-11-21-05-09&q;},&q;headers&q;:{&q;x-powered-by&q;:[&q;Express&q;],&q;x-ratelimit-limit&q;:[&q;500&q;],&q;x-ratelimit-remaining&q;:[&q;499&q;],&q;date&q;:[&q;Mon, 25 Nov 2024 20:47:30 GMT&q;],&q;x-ratelimit-reset&q;:[&q;1732568415&q;],&q;content-type&q;:[&q;application/json; charset=utf-8&q;],&q;content-length&q;:[&q;4394&q;],&q;etag&q;:[&q;W/\&q;112a-nsCCNvSyYXhNdw7icoVnPCw1MOk\&q;&q;],&q;connection&q;:[&q;keep-alive&q;],&q;keep-alive&q;:[&q;timeout=5&q;]},&q;status&q;:200,&q;statusText&q;:&q;OK&q;,&q;url&q;:&q;http://ntrs-proxy-auto-deploy:3001/citations/19940022186&q;,&q;responseType&q;:&q;json&q;}}</script></body></html>
