Abstract：
With the effective interactions consisting of a pairing force,a quadrupole pairing force and a quadrupole-quadrupole force among valence 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 good agreement with experiment,especially the data of first backbendings are reproduced satisfactorily.
