Description
The level structure of high-spin states of doubly odd nucleus 146Tb has been studied via the 118Sn (32S, 1p3n) 146Tb reaction using techniques of in-beam γ-ray spectroscopy. Measurements of γ-ray excitation functions, γ-ray anisotropies, X-γ and γ-γ-t coincidences were performed with 12 BGO (AC) HPGe detectors. Based on the gated spectra, γ-γ coincidence relationships, intensity balances and cross-over transitions, the level scheme in 146Tb has been extended up to an excitation energy of 8390 keV, and 41 new γ-rays are added into the level scheme. The spins for the new established levels have been assigned according to the results of the measured γ-ray anisotropies. The levels in 146Tb are interpreted qualitatively by coupling a h11/2 proton to a h11/2 neutron hole and πh11/2υh11/2-1 to the excited states in 146Gd core
