j壳层核子准旋、同位旋、角动量分类因子化重复度计算

CALCULATIONS OF FACTORIZED MULTIPLICITIES CLASSIFIED BY QUASISPIN,ISOSPIN AND ANGULAR MOMENTUM FOR j SHELL NUCLEONS

据群链［ＳＯ（５）Ｕ（１）ＤＳＵ（２）Ｔ］［Ｓｐ（２ｊ＋１）Ｏ（３）］，对ｊ壳层核子按广义准旋［ｓ，ｔ］、同位旋Ｔ、角动量Ｊ和核子数ｎ＝２Ｄ＋２ｊ＋１分类，分类重复度可因子化为ＳＯ（５）Ｕ（１）ＤＳＵ（２）Ｔ与Ｓｐ（２ｊ＋１）Ｏ（３）约化重复度之积。给出上述两个约化重复度的简明计算公式，并列出部分结果。

According to the group chain [SO(5)U(1) DSU(2) T][Sp(2j+1)O(3)], the coupling states of j shell nucleons are classified by D=(n 2j-1)/2 ,isospin T,angular momentum J and generalized quasispin[ s,t ],where s is generalized siniority and t is reduced isospin;the multiplicities classified are products of SO(5)U(1) DSU(2) T and Sp(2j+1)O(3) group reduction multiplicities.The explicit formulas for the two group reduction multiplicities are presented,and some results calculated are listed.
