摘要:
The nature of signature inversion in the πg9/2νh11/2 bands of odd-odd 98,102Rh nuclei is studied. Calculations are performed by using a triaxial rotor plus two-quasiparticle model and are compared with the experimentally observed signature inversions. The calculations reproduce well the observations and suggest that, in these bands,the signature inversion can be interpreted mainly as a competition between the Coriolis and the proton-neutron residual interactions in low K space.
