【摘要】 基于采用唯象核势的结团模型研究了铕同位素的α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α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α衰变半衰期的实验数据提取了相关系数.更多还原

【Abstract】 Based on the cluster model with phenomenologicalα-core potential,αdecay 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 phenomenologicalα-core nuclear potential.Using the existing experimental data ofαdecay half-life,the values of factor ffor europium isotopes are calculated.The results indicate that there is a strong linear correlation betweenfand isospin.And the correlation coefficients are also extracted.更多还原
