摘要: In this paper, the axial symmetry rotor plus quasiparticle model is generalized from odd nuclei to odd-odd nuclei. Energy spectra of yrast bands for 160Ho, 162Tm and 164Tm are calculated by using method. Signature inversions in these three reproduced, one possible signature inversion mechanism connected with calculation also discussed.
