超核激发态的对称性分类

我们把维格纳处理超级多重态的方法,推广用来研究超核激发态的能谱。给出了近似不破坏SU₆=SU₃?SU₂分类的两体相互作用普遍形式,并利用现有的散射实验数据定出了其中的系数。导出了在SU₆分类下,计算能量矩阵元的公式。并以⁹_ΛBe^*,¹⁰_ΛBe^*和¹⁰_ΛΛBe^*为例,进行了具体计算。理论上计算的⁹_ΛBe^*的能量与实验定性符合。

SYMMETRY CLASSIFICATION FOR EXCITED STATES OF HYPERNUCLEI

The method which Wigner used for the classification of supermultiplets has been generalized to the excited energy spectrum of hypernuclei. The general form of two-body interaction is obtained which approximately does not break the SU₆=SU₃?SU₂ classification and the coefficients in each of its term are determined from the experimental scattering data. The formula for the energy matrix element under SU₆ is also derived. For ⁹_ΛBe^*,¹⁰_ΛBe^* and ¹⁰_ΛΛBe^*, some concrete calculations aregiven. We find that ⁹_ΛBe^* states seem to agree qualitatively with experiment.
