摘要
本文在IBM-Ⅱ的框架下,以振动极限为例,讨论了M^1跃迁的两种机制:F旋破缺引起的跃迁和跃迁算符两体部分引起的跃迁。这为分析实际情形中究竟哪一种机制起主要作用提供了依据。
Two kinds of mechanism of M1 transitions are discussed in the vibrational limit case of IBM-Ⅱ. One is the transition caused by the breakage of F-spin, other caused by the two-body part of the transition operator. It is helpful to the investigation on the realistic M1 transitions of nuclei.
