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

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.
