摘要
利用量子散射理论———玻恩近似研究α粒子的散射问题,及散射原子核外电子的屏蔽效应和原子核的有限质量对散射截面的影响,对卢瑟福公式不能说明α粒子小角度散射,进行了修正,得到的结果和实验相符合.
The Rutherford formula cannot explain α -particle＇s small angle scattering question. This paper deals with this problem using the quantum scattering theory - born approximation, takes account of the influence of the shielding effect of the electron and limited quality of the atomic nucleus to scattering cross - section, carries on the revision to the Rutherford scattering formula according to experimental result.
