【摘要】 本文用折线图的微观理论定义0f-1p壳的“对”,并以这些“对”作为基础来构成⁴⁰Ca外有四个价中子的模型空间,计算了⁴⁴Ca的低能谱,结果表明,用这一模型空间大为缩小的简化模型,对具有同类价核子的⁴⁴Ca低能谱,只包括S,D,G和I“对”就能得到与实验值很好的符合更多还原

【Abstract】 Within the coupled-pair model space constructed through S,D,G and I "pair",which aredefined in f-p shell by means of the folded-diagram perturbation theory,the spectra of the statesof ⁴⁴Ca are calculated.The results show that for the nucleus having four identical valence-nuc-leons outside the core ⁴⁰Ca this truncated model space can reproduce the experimental low-lyingspectra of ⁴⁴Ca quite well.更多还原
