摘    要:在对反应总截面的理论计算中,现有的理论计算值与实验数据在高能区可以很好的符合,但在中能区理论值低于实验值约10%—20%.通过对计算核反应总截面的Glauber模型加入有限程修正,并对输入的核物质密度分布采用双参数的费米密度分布形式.计算结果表明,理论计算值对于没有奇异结构的核在低中能区和高能区,都与实验数据很好符合.

关 键 词:Glauber模型  双参数密度分布函数  反应总截面  非奇异结构核

Abstract:In the theoretical calculation of total reaction cross section, the results can fit the experimental data very well at high energy, but they are about 10%—20% lower at intermediate energy. In this work 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 nucleus. This shows that the results of the theoretical calculation are in agreement with the experimental one for non exotic structural nucleus, both at high and intermediate energy regions.
Keywords:Glauber model  Fermi  density  distribution function with two parameters  total reaction cross section  non-exotic structural nucleus
