A surprising asymmetric mass distribution of fission fragments from $^{180}$Hg, the daughter of $^{180}$Tl $\u03b2$ decays, was observed. Here, the energy calibration of the silicon detectors, which is crucial for a proper determination of the fission fragments\u2019 energy and mass split, is presented and the total kinetic energy and its dependence on the mass split ratio is discussed. A more precise $\u03b2$-delayed fission probability $P_{\u03b2\\textrm{DF}}(^{180}\\textrm{Tl})=3.2(2)\u00d710^{\u22123}%$ was deduced." }); // ]]> </script>  </div> </div> <div style="clear:both;margin-bottom: 0;"></div> </div> <div class="bottom-left"></div><div class="bottom-right"></div> </div> </div></div> <footer id="footer" class="pagefooter clearfix">  <div class="pagefooterstripeleft"> CERN Document Server :: <a class="footer" href="https://cds.cern.ch/?ln=pt">Pesquisar</a> :: <a class="footer" href="https://cds.cern.ch/submit?ln=pt">Submeter</a> :: <a class="footer" href="https://cds.cern.ch/youraccount/display?ln=pt">Personalizar</a> :: <a class="footer" href="https://cds.cern.ch/help/?ln=pt">Ajuda</a> :: <a class="footer" href="https://cern.service-now.com/service-portal?id=privacy_policy&se=CDS-Service" target="_blank">Privacy Notice</a> <br /> Powered by <a class="footer" href="http://invenio-software.org/">Invenio</a> <br /> Mantido por <a class="footer" href="https://cern.service-now.com/service-portal?id=service_element&name=CDS-Service">CDS Service</a> - Need help?
