The isotope shift measurements allowed tracking of changes in mean-squared charge radii across the deformed nuclear shell closure at N=152, whereby shape discontinuities were not observed. Experimental hyperfine coupling constants of the atomic ground state were combined with relativistic many-body atomic calculations to extract the nuclear magnetic-dipole moment of Cf249 with improved precision to μI(249Cf)=−0.395(17)μN, whereas μI(251Cf)=−0.571(24)μN and μI(253Cf)=−0.731(35)μN were derived for the first time. Additionally, the spectroscopic quadrupole moments QS(249Cf)=6.27(33)eb and QS(253Cf)=5.53(51)eb were extracted.</td></tr> <tr><td class="formatRecordLabel"> Copyright/License </td><td style="padding-left:5px;">publication: © 2023-2025 authors (License: <a href="https://creativecommons.org/licenses/by/4.0/">CC BY 4.0</a>)</td></tr> </table> <br/>Corresponding record in: <a href="http://inspirehep.net/record/2644747">Inspire</a> <small> </small> <br/> <br/><br/><div align="right"><div style="padding-bottom:2px;padding-top:30px;"><span class="moreinfo" style="margin-right:10px;"> <a href="" class="moreinfo">Back to search</a> </span></div></div> <div class="bottom-left-folded"><div class="recordlastmodifiedbox" style="position:relative;margin-left:1px"> 記錄創建於2023-04-22，最後更新在2024-09-27</div></div> <div class="bottom-right-folded" style="text-align:right;padding-bottom:2px;"> <span class="moreinfo" style="margin-right:10px;"><a href="/search?ln=zh_TW&p=recid%3A2856736&rm=wrd" class="moreinfo">相似記錄</a></span></div> </div> </div> </div> <br/> <br /> <div class="detailedrecordminipanel"> <div class="top-left"></div><div class="top-right"></div> <div class="inside"> <div id="detailedrecordminipanelfile" style="width:33%;float:left;text-align:center;margin-top:0"> <div><small class="detailedRecordActions">全文:</small> <br /><a href="/record/2856736/files/PhysRevC.107.034313.pdf"><img style="border:none" src="/img/file-icon-text-34x48.gif" alt="Download fulltext" /><br />PDF</a><br /></div> </div> <div id="detailedrecordminipanelreview" style="width:30%;float:left;text-align:center"> </div> <div id="detailedrecordminipanelactions" style="width:36%;float:right;text-align:right;"> <ul class="detailedrecordactions"> <li><a href="/yourbaskets/add?ln=zh_TW&recid=2856736">Add to personal basket</a></li> <li>Export as <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/hx?ln=zh_TW">BibTeX</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/hm?ln=zh_TW">MARC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/xm?ln=zh_TW">MARCXML</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/xd?ln=zh_TW">DC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/xe?ln=zh_TW">EndNote</a>,  <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/xn?ln=zh_TW">NLM</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2856736/export/xw?ln=zh_TW">RefWorks</a> </li> </ul> <div style='padding-left: 13px;'>  <div id="bookmark"></div> <div id="bookmark_sciencewise"></div> <style type="text/css"> #bookmark_sciencewise, #bookmark {float: left;} #bookmark_sciencewise li {padding: 2px; width: 25px;} #bookmark_sciencewise ul, #bookmark ul {list-style-image: none;} </style> <script type="text/javascript" src="/js/jquery.bookmark.min.js"></script> <style type="text/css">@import "/css/jquery.bookmark.css";</style> <script type="text/javascript">// <![CDATA[ $.bookmark.addSite('sciencewise', 'ScienceWise.info', 'https://cds.cern.ch/img/sciencewise.png', 'en', 'bookmark', 'http://sciencewise.info/bookmarks/cds:2856736/add'); $('#bookmark_sciencewise').bookmark({sites: ['sciencewise']}); $('#bookmark').bookmark({ sites: ['facebook', 'twitter', 'linkedin', 'google_plusone'], icons: '/img/bookmarks.png', url: 'https://cds.cern.ch/record/2856736', addEmail: true, title: "Nuclear moments and isotope shifts of the actinide isotopes Cf249\u2013253 probed by laser spectroscopy", description: "We report on high-resolution laser spectroscopy studies on Cf249\u2013253 with spectral linewidths in the order of 100\u00a0MHz carried out at the RISIKO mass separator at Mainz University. In total three atomic ground-state transitions were investigated and the hyperfine parameters for the odd-A isotopes and isotope shift for all examined isotopes have been determined from the measured spectra. The isotope shift measurements allowed tracking of changes in mean-squared charge radii across the deformed nuclear shell closure at N=152, whereby shape discontinuities were not observed. Experimental hyperfine coupling constants of the atomic ground state were combined with relativistic many-body atomic calculations to extract the nuclear magnetic-dipole moment of Cf249 with improved precision to \u03bcI(249Cf)=\u22120.395(17)\u03bcN, whereas \u03bcI(251Cf)=\u22120.571(24)\u03bcN and \u03bcI(253Cf)=\u22120.731(35)\u03bcN were derived for the first time.
