Moments Of Inertia Of Nuclei In Actinide And Rare-earth Regions In The Nilsson Mean-field Plus Nearest-Orbit Pairing Interaction Model

An exactly solvable mean-filed plus nearest-orbit pairing model for the description of well-deformed nuclei is used and applied to describe nuclei in actinide and rare-earth re-gions. By using proton and neutron Nilsson mean-field plus nearest-orbit pairing interactions among like nucleons, binding energies, pairing excitation energies, even-odd mass differ-ences of160-169Er,166-175Yb,172-181Hf,226-233Th,230-239U,236-243Pu are fetted, of which the results are used to calculate the moments of inertia of low-lying states of these even-even nuclei and odd-A nuclei. and compared with the corresponding experimental values. the moments of inertia of even-even nuclei and odd-A nuclei are also derived. The results show that, with reasonable deviations, the theoretical results agree to the corresponding ex-perimental results, which show that the model is suitable to be used to describe the binding energies, pairing excitation energies, even-odd mass differences, and moments of inertia of nuclei in both actinide and rare-earth regions.
