A～100区Tc同位素能级结构的研究

Study of Nuclear Level Structure in Tc Isotopes with Mass A～100

用投影壳模型对^(101)Tc的受激正/负宇称转晕态结构进行了探讨,为了从定量结果中抽取出物理内容也作出了正宇称转晕带的能带图．此外,各自起源于3/2^-[301]1,5/2^-[303]和1/2^+[431]尼尔逊态的3个带也在这个模型框架下进行了分析．到目前为止,在Z～42—44区关于N=52—54的中间核性质知之甚少,为了解这些“过渡核”,以^(95)Tc为例,对其能级结构也进行了研究．

In the present work, the structures of the excited positive/negative-parity yrast states of ^101Tc are discussed by using a projected shell model, and a band diagram calculated for the positive-parity yrast band is also shown in order to extract physics out of numerical results. In addition, the analysis of other three bands originated from 3/2^-[301],5/2^-[303], and 1/2^＋ [431] Nilsson states, respectively, is also performed in the framework of this model. Until recently,very little property about the N=52-54 intermediate nuclei in the Z -42-44 region has been known. In order to understand these ＂transitional nuclei＂, we select the nucleus ^95Tc as an example. So in this work, we also present our investigation of the level structure in the ^95Tc nucleus.
