本文通过分别对 sd-IBM4中的 O(6)极限 U(36)U_6(sd)×U_6(ST)O_6(sd)×O_6(ST)O_3(d)×O_3(S)×O_3(T)O_3(J)×O_3(T),强耦合 SU(3)极限 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)与 sdg-IBM4中的类SO(6)极限 U(90)U_(15)(sdg×U_6(ST)SU_(15)(sdg)×U_6(ST)U_5(sdg)×O_6(ST)SO_5(dg)×O_6(ST)O_3(dg)×O_3(S)×O_3(T)O_3(J)×O_3(T),强耦合 SU(3)极限 U(90)U_(15)(sdg)×U_6(ST)SU_(15)(sdg)×U_6(ST)SU_3(sdg)×SU_3(S)×SU_3(T)SU_3(sdgS)×SU_3(T)O_3(J)×O_3(T)的分析比较,表明 g 玻色子对 O(6)极限的典型能谱有较大的影响,当用类 O(6)极限同时拟合^(34)S 与^(34)Cl 的能谱时,对^(34)Cl 能得到很低的3_1^+态,而用 O(6)极限则不能,而且能谱结构也改变较大.但 g 玻色子对强耦合 SU(3)极限的低能态能谱与 E2跃进,则影响不大.
