Abstract：
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.
