摘　　要：用粒子数守恒方法（ＰＮＣ）来分析原子核在推转壳模型情况下，由阻塞效应而引起的准粒子剩余相互作用．计算结果表明，这种剩余相互作用除与费米面附近单粒子能级的分布，阻塞能级的位置有关外，还与旋转频率（ω）密切相关．在特定情形下，这种剩余相互作用的排斥性可转变为吸引性．The residual quasiparticle interaction due to the blocked effect is analyzed with the Particle-Num-ber-Conserving(PNC) method for treating Cranding Shell Model Hamiltonian. The calculation shows that this kind of residual interaction depends sensitively not only on the distribtion of the single-parti-cle levels vear the Fermi surface and the location of the blocked levels but aiso on the rotatonal fre-quency Under some conditions, the repulsive residual interaction may become attractive one.
