摘要

Attractive polarization effects are investigated in binary atomic Si-Si collisions. The eikonal method and effective potentials are used to obtain the phase shifts and cross sections for the atomic collisions as functions of the impact parameter and collision energy. The results show that the attractive polarization effect suppresses the phase shift and cross section. It is found that the maximum positions of the differential crass section approach the collision center owing to the attractive polarization effects. It is also found that the attractive polarization effects on the total eikonal cross section decrease with increasing collision energy.
