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 %— 2 0 % .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 .
In the theoretical calculation of the total reaction cross section, the existing theoretical and experimental data agree well with the experimental data in the high energy region, but the theoretical value in the mid energy region is lower than the experimental value by about 10% to 20% The modified Glauber model of the total cross-section of the nuclear reaction is modified by a finite-difference method, and the two-parameter Fermi density distribution is adopted for the density distribution of the input nuclear material. The calculated results show that for the nuclear without the singular structure, , Are in good agreement with the experimental data.
