实验上观测到丰中子偶偶碳同位素的2+1→0g.s.跃迁表现出很强的压低现象,而在丰质子一侧的碳同位素则表现出增强现象,丰中子碳同位素中还观测到跃迁的中子质子矩阵元之比Mn/Mp远超过标准壳模型计算值。我们用粒子振动模型研究了碳同位素的微观极化效应,并将之应用于计算碳同位素E2跃迁矩阵元。与核芯与传统的壳模型结果相比,我们给出了与实验更为一致的结果。我们 The experimentally observed 2 + 1 → 0g.s. Transitions of the even-even carbon isotopes of the neutron exhibit a strong depression while the carbon isotopes on the abundance proton side show an enhancement, The observed neutron proton matrix element ratio Mn / Mp far exceeded the calculated value of the standard shell model. We study the micro-polarization effect of carbon isotopes using the particle vibration model and apply it to the calculation of carbon isotope E2 transition matrix elements. Compared with the core and the traditional shell model results, we give more consistent results with the experiment. we
