| 摘 要： | 提出在中子－质子角动量耦合空间，通过群链间二次幺正变换，构造核子同位旋－角动量耦合波函数，并由此计算因子化的亲态比系数（ＣＦＰ）．用该方法完成了ｊ９／２的因子化ＣＦＰ全部计算，在４８６ＤＸ２微机上，ｊ＝７／２用１５ｓ，ｊ＝９／２用１２ｍｉｎ，表明该方法比已有方法高效

| Abstract: | In the paper, the isospin agular momentun coupling wave functions of nucleons are constructed by twice unitary transformations between group chains in agular momentun coupling space of neutron proton, the CFPs are factorized as products of three isoscalar factors(ISF) and the ISFs are calculated by using the coupling wave functions. It shows that the method is very efficient, on 486DX2 computer, the CPU time calculating all ISFs is 15 seconds for j=7/2, and 12 minutes for j=9/2 . |
