Abstract：
With the effective interactions consisting of a pairing force, a quadrupole pairing force and a quadrupole-quadrupole force among yalence nucleons, the microscopic approach based on the generalized Dyson expansion theory is applied in studying both the low-lying and high spin states for the isotones ¹⁵⁴Dy, ¹⁵⁶Er and ¹⁵⁸Yb. In the truncated state space, the configurations (sd)^N and (sd)^N-1 + neutron-pair are assumed, respectively, for the low-lying and high spin states, although the same values of strength parameters are taken in the numerical calculations in the two subspaces. The calculated results are in a good agreement with experiment. In particular, the data of first backbendings are reproduced satisfactorily.
