计算机模拟在高能背散射分析中的应用

Application of computer simulation to high energy backscattering analysis

系统总结了计算机模拟方法在高能背散射分析中的多种应用。通过应用测得的高能背散射截面数据，更新了ＲＵＭＰ程序的高能区数据库，将其扩展到高能背散射分析之中。文章除了通过实例阐明模拟方法的优势所在之外，还以４Ｈｅ－１２Ｃ背散射为例，说明了可以借助计算机模拟快速确定非卢瑟福背散射截面．

Various applications of computer simulation to high energy backscattering analysis were systemetically summarized.With the aid of the data measured in the accelerator lab at Fudan University,the data base of the computer simulation program RUMP was renewed to make it applicable to higher energy region.Some experimental results to elucidate superiority of the simulation were given and a new approach for quick calculation of non-Rutherford backscattering cross section based on the simulation principle was suggested.Experimental resultS of 4He-12C scattering were also presented.
