Study of the νi13/2－1 band in 189Pt

High-spin levels of 189Pt have been studied with the in-beam γ-spectroscopy method via the 176Yb(18O,5n) reaction at the beam energies of 88 and 95 MeV. The previously known νi-131/2 band has been confirmed, and its unfavored signature branch extended up to the 13/2+ state. Within the framework of the triaxial particle-rotor model, the νi-113/2 band is suggested to be associated with the 11/2[615] configuration, and to have triaxial deformation.

镜像核~(13)N-~(13)C和~(15)N-~(15)O中的激发态晕或皮(英文)

用非线性相对论平均场对两对镜像核13N 13C和15N 15O进行了研究. 发现无论在基态还是激发态, 用两套参数所得的结合能都跟实验值很接近. 计算结果显示13N的第一激发态 (2s1 /2 )和第三激发态(1d5 /2 )各存在一个非束缚的质子晕, 而13C的第三激发态 (1d5 /2 )存在一个弱束缚的中子皮. 另外研究表明, 在另一对镜像核15N 15O的第二激发态 (2s1 /2 )和第一激发态 (2s1 /2 )分别存在一个中子晕和质子皮.
