摘要/Abstract

摘要： 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。

Abstract: 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-2 j-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.
