Abstract：
High-spin Level structure of ¹⁴⁶Tb has been studied via the ¹¹⁸Sn(³²S,1p3n)¹⁴⁶Tb reaction using techniques of in-beam γ-ray spectroscopy. 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. The doubly odd nucleus ¹⁴⁶Tb has one proton-particle and one neutron--hole with respect to the doubly closed nucleus ¹⁴⁶Gd, and its low-lying states should be 2-qp states, and the high-lying states should be 4-qp states or the coupling of 2-qp state to the low-lying excited states in ¹⁴⁶Gd core. The excitation of the fully-aligned 4-qp configurations can also be well reproduced using the empirical shell-model approaches.
