Multi-quasiparticle Excitations in 145Tb

  • High-spin states in 145Tb have been populated using the 118Sn(32S, 1p4n) reaction at a beam energy of 165MeV. The level scheme of 145Tb has been established for the first time. The level scheme shows characteristics of spherical or slightly oblate nucleus. Based on the systematic trends of the level structure in the neighboring N=80 isotones, the level structure in 145Tb below 2MeV excitation is well explained by coupling an h11/2 valence proton to the even-even 144Gd core. Above 2MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.

Abstract: High-spin states in 145Tb have been populated using the 118Sn(32S, 1p4n) reaction at a beam energy of 165MeV. The level scheme of 145Tb has been established for the first time. The level scheme shows characteristics of spherical or slightly oblate nucleus. Based on the systematic trends of the level structure in the neighboring N=80 isotones, the level structure in 145Tb below 2MeV excitation is well explained by coupling an h11/2 valence proton to the even-even 144Gd core. Above 2MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.
