摘要: We have studied the properties of decoupled band in particular odd-A nuclei, and results provide information on origin backbending even- even nuclel. Our data are agreement with rotation-alignment model apparent disagreeement pairing-collapse model. This proposed test also provides a means to determine which particles involved two- quasiparticle that intersects ground picture backbending. (auth)
