Ar原子与H_2低能碰撞分波截面的理论研究

Theoretical calculation of scattering cross sections in Ar-H_2 collision

使用Tang-Toennies势模型通过密耦近似(Close-Coupling)方法计算了Ar原子与H2分子在碰撞能量分别为E=0.15eV、0.25eV、0.35eV时的分波截面,对计算结果进行了讨论,总结了该碰撞体系的弹性微分截面(00-00)以及分波散射截面在弹性散射00-00和非弹性散射00-02、00-04的变化规律。

The differential scattering cross sections of He, Ne and Ar-H2 collisions have been calculated by close-coupling approximation method using Tang-Toennies potential model in different incident atomic energy. At the same time, the result of the calculation is discussed and the changing regularities of the scattering cross sections are summed up.
