摘　　要：利用Glauber模型对奇异核的反应总截面进行计算时 ,对模型进行了有限程修正和库仑修正 ,并对奇异核输入的密度采用了核芯加价核子的形式 ,使得理论与实验在中高能下都得到了很好的符合 .In order to fit the total reaction cross section of exotic nuclei, by using Glauber model,we consider that the exotic nuclei is composed of a core and valence nucleon(s), the finite range correction has been added to the Glauber model, and a Fermi density distribution with two parameters has been chosen as the input density distribution of the core of the exotic nucleus for the special distribution of the valence nucleon(s), has a large dispersion. The results of the theoretical calculation are in agreement with the experimental one for nucleus with exotic structure, both at high and intermediate energy regions.
