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.
