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
