Abstract：
Formulae for the nuclear pairing-rotational (p.r.) and pairing-vibrational (p.v.) spectra are obtained using the PNC (particle-number-conserving) method. The quentum numbers characterizing the p.r. band, the braching ratios and the selection rule for two-particle transfer reactions are given. It is shown that the pairing-rotational scheme holds even for those nuclei near closed-shell, provided that the major-shell is not crossed. The anharmonic p.v. spectrum is shown to be equivalent to two sets of p.r. bands. The physical meaning of the parameters occuring in the p.r. and p.v. spectra is discussed.
