摘要
The collective rotations of the K^π=5^- configuration in neutron-rich Mo, Ru and Pd isotopes were systematically investigated by the configuration-constrained cranking shell model based on the Skyrme Hartree-Fock method with pairing treated by shell-model diagonalization. The calculations efficiently reproduce the experimental moments of inertia of both the ground-state and side bands. Rotational bands built on two-particle K^π=5^- configurations have been the subject of intense study. Possible configurations were assigned to the observed 5^- bands in ^102-106Mo,^108-112Ru and ^112-114Pd. We predict the existence of the 5^- bands in ^108,110Mo. These results provide deep insights into the structure of neutron-rich nuclei, and provide useful information for future experiments.
