摘要

摘要对90Nb核进行了壳层模型计算,模型空间中价质子占据f5/2、p3/2、p1/2和g9/2轨道,价中子占据p1/2、g9/2、d5/2和g7/2轨道。根据计算结果,负宇称来自f5/2、p3/2和p1/2轨道的质子的贡献。90Nb的中等自旋态主要是由于质子从f5/2和p3/2轨道激发到穿过Z=38亚壳层闭合的p1/2和g9/2轨道,而高自旋态则是由于单个中子从g9/2轨激发到穿过N=50壳层闭合的d5/2轨道。

Investigation of the level structure of 90Nb nucleus using the shell model
Abstract Shell model calculations have been carried out for 90Nb nucleus with the model space in which the valence protons occupy the f5/2, p3/2, p1/2, and g9/2 orbitals and the valence neutrons occupy the p1/2, g9/2, d5/2, and g7/2 orbitals. According to the calculated results, the negative parity is from the contribution of the proton of the f5/2, p3/2, and p1/2 orbits. The moderate spin states of 90Nb are mainly due to the excitation of protons from the f5/2 and p3/2 orbits to the p1/2 and g9/2 orbits across the Z = 38 subshell closure, and the high spin states arise from the excitation of a single neutron from the g9/2 orbit into the d5/2 orbit across the N = 50 shell closure.
