Band structure of doubly-odd Tc and Rh isotopes

摘要

The △I = 1 doublet bands built on the vh_(11/2) πg_(9/2) configuration for the doublyodd Tc and Rh isotopes are investigated within the framework of a simple model, the quadrupole coupling model (QCM) [1,2]. In the model, a system of one neutron in the orbital iy and one proton in the orbital in is specified as the state , where L is the angular momentum of the two particle state. The collective-core state is denoted as , where R indicates the angular momentum of the core state. A total wave function of any doubly-odd nucleus is written as a product of the collective-core state and two particle state, where I is the total spin. The model Hamiltonian employed in the present calculation consists of the Hamiltonian of the collective core and the quadrupole-quadrupole interactions between the collective core, the neutron, and the proton.
