通过铕同位素的alpha衰变研究核势的同位旋效应

Study of the Isospin Effect of Nuclear Potential with alpha Decay of Europium Isotopes

摘要:

基于采用唯象核势的结团模型研究了铕同位素的alpha衰变半衰期，计算结果表明结团模型比库仑势加亲和势模型更加接近铕同位素的alpha衰变实验数据. 引入因子f来修正唯象核势，发现因子f与同位旋之间存在强烈的线性关系，根据alpha衰变半衰期的实验数据提取了相关系数.

Abstract:

Based on the cluster model with phenomenological alpha-core potential,alpha decay half-life of europium isotopes are investigated. The calculated results indicate that cluster model is more appropriate for europium isotopes than the Coulomb and Proximity Potential Model. In order to study the isospin effect of nuclear potential, we introduce the factor f, which is used to modify phenomenological alpha-core nuclear potential. Using the existing experimental data of alpha decay half-life, the values of factor f for europium isotopes are calculated. The results indicate that there is a strong linear correlation between f and isospin. And the correlation coefficients are also extracted.
