摘要: 本文在α粒子一次散射理论的基础上,进一步考虑了第二个原子对散射概率的贡献,建立了散射角与各散射参数间的关系.通过改变α粒子的入射能量以及两原子的位置参量,较好地模拟了各种情况下的散射概率随散射角的分布情况.

Abstract: Based on a single scattering theory of alpha particle, the contribution to the total scattering from the second atom are included, and the relationship among the scattering angle and other scattering parameters is established. By adjusting the scattering parameters,such as incident energy of alpha particle and the position parameter of tow atoms, the distribution of scattering probability in different conditios is simulated.

Key words: scattering probability, scattering angle, Rutherford scattering formula
