Rydberg态Na原子与稀有气体热碰撞的l-混合截面的计算

CALCULATION OF l-MIXING CROSS SECTION IN THERMAL COLLISION OF RYDBERG STATE Na ATOM WITH RARE GAS

本文在冲击近似方法基础上,采用一种有解析解的唯象势波函数计算了Rydberg态Na原子与稀有气体原子(He,Ne,Ar)热碰撞的l-混合跃迁截面。Na-He的计算结果与其它方法相比有显著改进。

On the basis of impulse approximate method, an analytical wavefuction based on a potential model was used to calculate the l-mixing transition cross section of Rydberg state Na atom in thermal collision with He, Ne and Ar, the results for Na-He are better than that of other methods ever used.
