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

  • 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.

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.
