The level structure of doubly odd nucleus 146Tb has been studied via the 118Sn(32S, 1p 3n)146Tb reaction by using techniques of in-beam γ-iay spectroscopy. Measurements of 7-ray excitation functions, 7-ray anisotropies, X-γ and γ-γ-t coincidences were performed with 12 BGO(AC)HPGe detectors. Based on the γ-γ coincidence relationships, intensity balances and cross-over transitions, the level scheme of 146Tb has been extended up

Study of in-beam γ-ray spectroscopy of 146Tb has been carried out by using the 118Sn(32S,1p3n)146Tb reaction. Based on the experimental measured results, the level scheme of 146Tb has been revised significantly and extended up to an excitation energy of 8.39 MeV. Preliminary results of the present work have been reported in a letter. The level structure shows characteristics of a spherical nucleus. The odd-odd nucleus 146Tb has one proton-particle and one neutron-hole with respect to the doubly closed nucleus 146Gd, and its low-

Study of in-beam γ-ray spectroscopy of ^145Tb has been carried out by using ^118Sn (32 S, 1p4n) ^145Tb reaction. Excitation functions, X-γ-t and γ-γ-t coincidences and γ-ray anisotropies were measured. Here, t refers to the relative time difference between any two coincident γ-rays detected within ±200 ns. A level scheme of ^14tTb, including 81 γ-transitions as shown in Fig.l, has been established up to 7.4 MeV in excitation energy and spinparity assignments for most of the observed levels have been done. The level structure shows characteristics of spherical nucleus. The observed states with excitation energies less than 2 MeV are interpreted by coupling an h11/2 proton to the 2^+, 4^+ and 3^- core excitations in ^144Gd. The excitation energies of these states fit wellin to the systematics of the neighboring odd-A N=80 isotones, and are well reproduced by the quasiparticle-cluster interaction calculations[1]. Semi-empirical shell model calculations[2] have been done for the higher-lying levels. The results clearly reveal the characteristic features of multiparticle configurations in a spherical nucleus. Specific configurations are proposed for the yrast and some non-yrast levels.
