摘要
在IBM4中,当存在s、d、g玻色子时,体系的对称性群为U(90).本文研究了子群链:U_(90)(?)U_(15)(sdg)×U_6(ST)(?)SU_(15)(sdg)×U_6(ST)(?)SU_5(sdg)×O_6(ST)(?)SO_5(dg)×O_3(S)×O_3(T)(?)O_3(dg)×O_3(S)×O_3(T)(?)O_3(J)×O_3(T),给出了约化规则和典型能谱,并在轻核中找到了具有这种动力学对称性的能谱的例子,偶偶核^(34)S与奇奇核^(34)Cl在一个多重态中.
In the IBM4, when s. d. g bosons are presented, the symmetry group of the system is U(90). in this paper, the group chain. U_(90)(?)U_(15)(sdg)×U_6(ST)(?)SU_(15)(sdg)×U_6(ST)(?)SU_5(sdg)×O_6(ST)(?)SO_5(dg)×O_3(S)×O_3(T)(?)O_3(dg)×O_3(S)×o_3(T)(?)O_3(J)×O_3(T)is diseussed, the reduction rules and the typical energy spectra are obtained. An example of a spectrum with this dynamical symmetry is found out, where the even-even nucleus ^(34)S and oddodd nucleus ^(34)Cl are in one multiplet.
