High Spin States in Odd-odd ~(172)Re

Keywords： rotational band , two-quasiparticle configuration , quasiparticle alignment , odd-odd nucleus (172)~Re

对~(149)Sm(~(27)Al,4n)~(172)Re反应产生的~(172)Re在束γ的实验数据进行了重新分析,新发现了可归属于~(172)Re的3个转动带,由此建立了由6个转动带构成的~(172)Re高自旋态能级纲图.依据相邻核的带结构知识和推转壳模型分析方法,对新发现的3个转动带的准粒子组态进行了指定,讨论了它们的转动特征.

We have re-analyzed the experimental data of in-beam γ spectroscopy for ~(172)Re via the ~(149)Sm(~(27) Al,4n)~(172)Re reaction.Three rotational bands have been newly found and assigned to ~(172)Re.A new level scheme of ~(172)Re,consisting of 6 bands,is thus presented.Based on the existing knowlegde from the neighboring nuclei and the cranked shell model,the quasiparticle configurtions have been assigned to the 3 newly observed bands and their structure properties have been dicussed.
