Abstract：
The level structure of high-spin states of doubly odd nucleus ^l46Tb has been studied via the ¹¹⁸Sn (³²S, 1p3n) Tb reaction using techniques of in-beam y-ray spectroscopy. Measurements of r-ray excitation functions, y-ray anisotropies, X-r and r-r-t coincidences were performed with 12 BGO(AC)HPGe detectors. Based on the gated spectra, r-r 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 7-rays are added into the level scheme. The spins for the new established levels have been assigned according to the results of the measured 7-ray anisotropies. The levels in ¹⁴⁶Tb are interpreted qualitatively by coupling a h_11/2 proton to a h_11/2 neutron hole and h_11/2 υ h11/2^－1 to the excited states in ¹⁴⁶Gd core.
