A new formula of nuclear charge radii

Based on the systematic investigation of the data available, a Z(1/3) law for nuclear charge radii is shown to be superior than the generally accepted A(1/3) law. The Z(1/3) law describes data very well for the nuclei close to the beta-stability line, while an approximate linear dependence of isospin must be added when it is applied to the nuclei far from the beta-stability line. A new isospin dependence Z(1/3) formula thus obtained is proved to be more effective to describe the charge radii data. The collective behavior of the light and heavy nuclei has been discussed.Physics, NuclearPhysics, Particles & FieldsSCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)13252-2582
