Axially-symmetric quadrupole-octupole constrained self-consistent mean-field (SCMF) calculations with a choice of universal energy density functional are performed for those nuclei such as light actinides, Xe, Ba, Ce, and Nd isotopes from proton-rich to neutron-rich sides, and neutron-rich Ge, Se, and Kr, in which enhanced octupole correlations are expected to occur. Low-energy positive- and negative-parity spectra and transition strengths are computed in terms of the interacting boson model, with the parameters determined by the constrained SCMF calculations. Octupole-deformed equilibrium states are found in the potential energy surfaces of the nuclei in the regions corresponding to the neutron or\/and proton numbers equal to 34, 56, 88, and 134. The evolution of the calculated spectroscopic properties indicate the onset of octupole deformation and exhibit signatures of octupole shape-phase transitions around these nucleon numbers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Place: Nishina Hall, RIKEN Wako Campus + hybrid https:\/\/u-tokyo-ac-jp.zoom.us\/meeting\/register\/tZUlfuGvpjIvE9Y [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[210],"class_list":["post-3730","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-event"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/posts\/3730","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/comments?post=3730"}],"version-history":[{"count":0,"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/posts\/3730\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/media?parent=3730"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/categories?post=3730"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cns.s.u-tokyo.ac.jp\/cns\/wp-json\/wp\/v2\/tags?post=3730"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
