A complex fine-structure α-decay pattern of $^{180}$Au was deduced, providing insight into the low-lying levels in the daughter nucleus $^{176}Ir$. An $α$-decay branching ratio of $b_α$($^{180}$Au)=0.58(10)% and a half-life of $T_{1/2}=7.2(5)$s have also been derived, allowing for the calculation of the reduced α-decay widths and determining the degree of hindrance of respective $α$-decay branches. From complementary first in-source laser spectroscopy measurements of the hyperfine structure in atomic transitions of $^{180,182}$Au, the nuclear magnetic moments of $μ$($^{180}$Au)=−0.83(9)$μ_N$ and $μ$($^{182}$Au)=1.66(9)$μ_N$ were extracted with an inclusion of a correction for the hyperfine anomaly. Based on the observed hyperfine structure patterns, and on the comparison of the measured and calculated $μ$ values, a preferred ground-state spin and parity $I^π(^{180}\textrm{Au}^{gs}=(1^+)$ is proposed, and the earlier assignment of $I^π(^{180}\textrm{Au}^{gs}=(2^+)$ is confirmed. For $^{182}$Au, the most probable proton-neutron Nilsson configuration of $π3/2^−[532]⊗ν5/2^−[512]$ suggests the same proton state as in the heavier deformed odd-odd nuclei $^{180,184}$Au.

A complex fine-structure α-decay pattern of $^{180}$Au was deduced, providing insight into the low-lying levels in the daughter nucleus $^{176}Ir$. An $α$-decay branching ratio of $b_α$($^{180}$Au)=0.58(10)% and a half-life of $T_{1/2}=7.2(5)$s have also been derived, allowing for the calculation of the reduced α-decay widths and determining the degree of hindrance of respective $α$-decay branches. From complementary first in-source laser spectroscopy measurements of the hyperfine structure in atomic transitions of $^{180,182}$Au, the nuclear magnetic moments of $μ$($^{180}$Au)=−0.83(9)$μ_N$ and $μ$($^{182}$Au)=1.66(9)$μ_N$ were extracted with an inclusion of a correction for the hyperfine anomaly. Based on the observed hyperfine structure patterns, and on the comparison of the measured and calculated $μ$ values, a preferred ground-state spin and parity $I^π(^{180}\textrm{Au}^{gs}=(1^+)$ is proposed, and the earlier assignment of $I^π(^{180}\textrm{Au}^{gs}=(2^+)$ is confirmed. For $^{182}$Au, the most probable proton-neutron Nilsson configuration of $π3/2^−[532]⊗ν5/2^−[512]$ suggests the same proton state as in the heavier deformed odd-odd nuclei $^{180,184}$Au.</td></tr> <tr><td class="formatRecordLabel"> Copyright/License </td><td style="padding-left:5px;">publication: © 2020-2024 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/1811542">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"> Record created 2020-08-30, last modified 2020-08-30</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=pt&p=recid%3A2729189&rm=wrd" class="moreinfo">Registos similares</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">Fulltext from publisher:</small> <br /><a href="/record/2729189/files/PhysRevC.102.024312.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=pt&recid=2729189">Add to personal basket</a></li> <li>Export as <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/hx?ln=pt">BibTeX</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/hm?ln=pt">MARC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/xm?ln=pt">MARCXML</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/xd?ln=pt">DC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/xe?ln=pt">EndNote</a>,  <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/xn?ln=pt">NLM</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2729189/export/xw?ln=pt">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:2729189/add'); $('#bookmark_sciencewise').bookmark({sites: ['sciencewise']}); $('#bookmark').bookmark({ sites: ['facebook', 'twitter', 'linkedin', 'google_plusone'], icons: '/img/bookmarks.png', url: 'https://cds.cern.ch/record/2729189', addEmail: true, title: "Laser-assisted decay spectroscopy for the ground states of $^{180,182}$Au", description: "A study of the ground states of the laser-ionized and mass-separated odd-odd isotopes $^{180,182}$Au was performed using the Resonance Ionization Laser Ion Source, Windmill detection setup and ISOLTRAP Multi-Reflection Time-of-Flight Mass Spectrometer at ISOLDE, CERN.
