The high spin state of 145 Tb was produced by the reaction of 118Sn (32S, 1p4n) with the 32S beam with energy of 1 61- 1 75MeV.The excitation function of γ-ray and γγt coincidence measurement were proposed.Firstly, 4 energy levels and 42 2 γ transitions, and assigned the spins of some energy levels and the parity of some lower energy levels.A πh11 / 2 valence proton and 144 The coupling of Gd core excited states qualitatively explains some of the lower excited states of 145 Tb
