摘要: 通过对中能区和相对论能区反应总截面的比较， 可对了解核中核子密度分布的尾巴分量提供重要的信息， Ｇｌａｕｂｅｒ 模型的计算总是低估中能区的反应总截面， 对中子晕核和中子皮核， 这种低估更为严重． 因此， 基于 Ｇｌａｕｂｅｒ 模型从反应总截面提取核的大小存在着一些问题． 对一些轻的奇异核进行中能区核反应总截面的激发函数测量可能会有助于上述问题的解决.A comparison of interaction cross section at relativistic and intermediate energy provides important information about the existence of tail component in the density distribution. The Glauber model calculation always underestimates the total reaction cross section at intermediate energy. The differences are enhanced for halo and skin nuclei. The method to extract the size of nuclei via Glauber model seems to have some ambiguity. The excitation function of total reaction...
