Applications Of Nilsson And Relativistic Mean-field Plus Nearest-orbit Pairing Interaction Model To Well-deformed Nuclei

An exactly solvable Nilsson and relativistic mean-field plus nearest-orbit pairing model for the description of well-deformed nuclei is used and applied to rare-earth and actinide regions. Binding energies, pairing excitation energies, and even-odd mass differences of ~227-233ph, 232-239u; 236-243pu isotopes and 158-171 Er 165-178Yb; 171-183Hf isotopes are calculated and compared with the corresponding experimental values. Nnclear moment of inertia in the model is also derived. As an approximation, pairng interaction between protons and neutrons, and the quadrupole-quadrupole interaction are not considered. It is inferred that the theoretical results of binding-energies, lower-lying pairing excitation energies and values of moment of inertia of rare-earth and actinide nuclei are basically close to the corresponding experimental values when nearest orbit proton and neutron pairing interactions are assumed.
