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 h _11/2valence proton to the even-even ¹⁴⁴Gd core. Above 2MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.
