Study of level structure in Tb-146

the level structure of high-spin states of doubly odd nucleus tb-146 has been studied via the sn-118 (s-32, 1p3n) tb-146 reaction using techniques of in-beam gamma-ray spectroscopy. measurements of gamma-ray excitation functions, gamma-ray anisotropies, x-gamma and gamma-gamma-t coincidences were performed with 12 bgo (ac) hpge detectors. based on the gated spectra, gamma-gamma coincidence relationships, intensity balances and cross-over:transitions, the level scheme in tb-146 has been extended up to an excitation energy of 8390 kev, and 41 new gamma-rays are added into the level scheme. the spins for the new established levels have been assigned according to the results of the measured gamma-ray anisotropies. the levels in tb-146 are interpreted qualitatively by coupling a h(11/2) proton to a h(11/2) neutron hole and pi h(11/2) v h(11/2)(-1) to the excited states in gd-146 core.
