                                 Abstract:In this paper the particle-number-conserving method (PNC) for treating pairing correlations in deformed nucleus is extended to treat the spherical nucleus. The properties of the ground state and the lowlying 0+ states of even-even isotops nearby 208Pb are calculated with this method.
