摘要
采用以玻色子展开和ＭＪＳ（ＭｏｄｉｆｉｅｄＪａｎｃｏｖｉｃｉ－Ｓｃｈｉｆｆ）代换为基础的微观ＩＢＭ－２方案，用直接对角化的计算方法，研究￣＊（１０８－１１８）Ｃｄ偶同位素集体能谱．计算结果与实验能谱作了比较，并对近满壳偶偶核中价质子空穴激发特性及影响能谱结构的因素作了讨论．
The low-lying collective energy spectra of cadmium even isotopes are calculated exactly by means of microscopic IBM-2 approach which is based on the Dyson boson expansion and the modified Jancovici-Schiff substitution. The exciting properties of valence proton hole are-analyzed.The results show that the mixed-symmetry states and full-symmetry states of cadmium even isotopes are well described by IBM-2.
