对双奇核~(174)Re的在束γ谱学实验数据作了仔细分析,提取出了带间与带内E2 γ跃迁分支比,并导出了其约化跃迁概率的比值.用带混合理论对约化跃迁概率的比值进行了分析,得到带间相互作用强度及转动带形变的信息.发现不同组态的转动带其跃迁电四极矩具有明显的差异.与相邻奇A核的结构特征类似,这种跃迁电四极矩的差异很可能是由于1/2~-[541]准质子或1/2~-[521]准中子对原子核的形状驱动效应造成的.
By analyzing carefully the in-beam γ spectroscopy data of odd-odd ~(174)Re,we have extracted the branching ratios of the interband and intraband E2 γ transitions from the two rotational bands of different configurations in ~(174)Re.The ratios of the reduced transition probabilities B(E2)have been deduced and an-alyzed using a band mixing theory.Information on the band interaction and deformation have been ob-tained.Apparent differences of transition quadrupole moments are found in the two configurations.A like-ly reason for the differences in the transition quadrupole moments is the shape driving effects of 1/2~-[541] quasi-proton or 1/2~-[521]quasi-neutron,which has been proposed in the odd-A neighbors of ~(174)Re.
