改进的Glauber理论和核–核反应总截面

利用Glauber理论系统计算了中、低能条件下核–核反应总截面.讨论了量子效应、库仑效应以及核子–核子碰撞同位旋效应对Glauber理论的修正.发现在应用Glauber理论计算中、低能核–核反应截面时,量子修正是重要的.利用修正了的Glauber理论,系统计算了从低能到高能大量稳定线附近的核–核反应总截面,在没有可调参数的情况下,都与实验结果较好地符合.

Improved Glauber Theory and the Total Reaction Cross Section of the Nucleus-Nucleus Collision

An improved Glauber theory for calculalions of the total reaction cross section at low and medium energies is proposed. The quantum effect,Coulomb effect and isospin effect of nucleon nucleon collision inclnded in the improved Glauber theory are discussed under the assumption of the effective nuclear density distribution. It is found that quantum corrections is very important when the Glauber theory is applied to calculations of the nucleus nucleus reaction cross. The calculated results obtained with the improved Glauber theory are in agreement with the experimental data in ten percent without any free parameters,which demonstrate the improved Glauber theory to be a pragmatic approach for calculating total nucleus nucleus reaction cross sections in the low and intermediate energy regions
