Abstract：
Identical one-quasiparticle and two-quasiparticle bands in neighboring odd-and even-mass nuclei are recognized.The intrinsic structure of identical bands is demonstrated by using the particle-number-conserving(PNC) treatment.The occurrence of almost identical moments of inertia is the result of competition among the shell effect (including shape variation),pairing(anti-alignment)effect and blocking (anti-pairing) effect.The observed moments of inertia of identical multi-quasiparticle bands are reproduced quite well by the PNC calculation.
