Abstract：
High-spin states of ¹⁵²Gd have been studied via the ¹⁴⁸Nd( ⁹Be, 5n) ¹⁵²Gd fusion-evaporation reaction. The ground-state band, octupole band and β band have been extended up to spins 20 ⁺, 21 ^－and 16 ⁺, respectively. A possible aligned two quasi-neutron band, was observed for the first time. The kinematic behaviors of the ground-state bands and yrast bands in ^152,154Gd indicate that the shape of ¹⁵²Gd may change with the increasing of rotational frequency, which are consistent with the theoretical calculations using Cranked Woods-Saxon-Strutinsky methods. The first band crossing observed in ¹⁵²Gd can be ascribed to the alignment of a pair of i _13/2neutrons.
