IBM4中的强耦合SU(3)极限

The Strong Coupling SU(3) Limit in IBM4

将IBM推广应用于轻核时叫IBM4。本文讨论了其中的下述群链。 U(36)(?)U_6(sd)×U_6(ST)(?)SU_3(sd)×SU_3(S)×SU_3(T)(?)SU_3(sdS)×SU_3(T)(?)O_3(J)×O_3(T)的约化、典型能谱与E2跃迁,并用它对彬壳的核基态进行了分类.

When the IBM is generalized and used to the case of light nuclei, it is called IBM4. In this paper, for the following group chain of the IBM4 U(36)U_6(sd)×U_6(ST)SU_3(sd)×SU_3(S)×SU_3(T) SU_3(sdS)×SU_3(T)O_3(J)×O_3(T) the reduction rules, typical energy spectra and E2 transitions are discussed. Using this strong coupling SU(3) limit, the nuclei in sd shell are classified.
