Description

High-spin states in 145Tb have been investigated by means of in-beam γ-ray spectroscopy techniques with the 118Sn(32S, 1p4n) reaction. Excitation functions, X-γ-t and γ-γ-t coincidences and γ-ray anisotropies were measured. A level scheme of 145Tb was established up to Ex∼ 7 MeV. The level structure shows characteristics of a spherical nucleus. Based on the systematics of level structure in the odd-A N = 80 isotones, the level structure below 2 MeV excitation is interpreted by coupling an h11/2 proton to the excitations in the even-even 144Gd core. Above 2 MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations
