Mean-Field Plus Nearest-Orbit Proton-Proton and Neutron-Neutron Pairing Interaction Model and the Unified Description of Actinide Nuclei

  • An exactly solvable mean filed plus nearest orbit proton proton and neutron neutron pairing interaction model for the unifled description of well deformed nuclei in actinide region is proposed.Binding energies,pairing excitation energies,and even odd mass differences of 227-233Th,232-239U,236-243Pu isotopes and 228Ra-229Ac-230Th-231Pa-232U,232Th-233Pa-234U-235Np-236Pu,and 236U-237Np-238Pu-239Am isotones are calculated and compared with the corresponding experimental values.

Abstract: An exactly solvable mean filed plus nearest orbit proton proton and neutron neutron pairing interaction model for the unifled description of well deformed nuclei in actinide region is proposed.Binding energies,pairing excitation energies,and even odd mass differences of 227-233Th,232-239U,236-243Pu isotopes and 228Ra-229Ac-230Th-231Pa-232U,232Th-233Pa-234U-235Np-236Pu,and 236U-237Np-238Pu-239Am isotones are calculated and compared with the corresponding experimental values.
