Abstract：
The exactly solvable Nilsson mean-field plus nearest-orbit pairing model is applied to describe nuclei in actinide and rare-earth regions. Binding energies, pairing excitation energies, even-odd mass differences, and moment of inertia of low-lying excitation states for even-even nuclei of ^226—234Th, ^230—239U, ^236—243Pu, ^160—170Er, ^166—176Yb, ^172—180Hf are calculated in both proton-proton and neutron-neutron pairing and proton-proton pairing excitation frozen cases, and compared with the corresponding experimental data.
