High-spin states in 145Tb have been populated using the 118Sn (32S, 1p4n) reaction at beam energy of 165 MeV. The level scheme of 145Tb has been established up to Ex ≈7.4 MeV. The level scheme shows characteristics of a 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 2 MeV excitation is well explained by coupling an h11/2valence proton to the even-even 144Gd core. Above 2 MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.

In-beamγ-ray spectroscopic experiment for the deformed odd-A nucleus 179Pt has been performed via the 149Sm(35Cl, p4n) reaction at beam energy of 180 MeV. The 35Cl beam was provided by the tandem accelerator at the Japan Atomic Energy Research Institute (JAERI). The target was an isotopic 149Sm foil of 1. 5 mg /cm2 thickness with a 5 me/cm2 Pb backing. Based on the measured results, three rotational
