摘　　要：对149Sm(27Al,4n)172Re反应产生的172Re在束γ的实验数据进行了重新分析,新发现了可归属于172Re的3个转动带,由此建立了由6个转动带构成的172Re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 ^172Re via the ^149Sm（^27Al,4n）^172Re reaction.Three rotational bands have been newly found and assigned to ^172Re.A new level scheme of ^172Re,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.
