K~π=5~- rotational bands in neutron-rich Mo,Ru,and Pd nuclei

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 ~(102-106) Mo,~(108-112) Ru and ~(112-114) Pd.We predict the existence of the 5~-bands in ~(108,110) Mo.These results provide deep insights into the structure of neutron-rich nuclei,and provide useful information for future experiments.
