Abstract The studies of the deformed nucleus for the Pb isotopes in the A~190 re- gion has been carried out by using the P.S.M. The comparison between the theoretical calculation of the transition energy, kinetic moment of ine- rtia, dynamic moment of inertia, paring gap, rotational energy, quadrupole moment, and B(M1)/B(E2) and the experiment observations are presented. We found that the kinetic moment of inertia is increased as the spin incre- ase for the even-even nuclei. This rise has been interpreted as being due to the combined alignment of the quasiparticles in the high-N intruder or- bit. And the kinetic moment of inertia is constant function of spin in the odd-even nuclei. It is interpreted as been due to the Pauli blocking of odd -quasineutron in the high-N intruder orbit.
