里德伯Cs原子与CCl4分子的碰撞电离研究

为描述里德伯Ｃｓ原子与ＣＣｌ４分子碰撞电离实验研究中所发现的若干特征，对里德伯原子与分子碰撞的理论模型－准自由电子模型提出两点修正：（１）考虑原子实在碰撞过程中的作用，并且计入量子亏损；（２）考虑碰撞后正负离子的分离几率。利用修正的模型进行了理论计算，得到了与实验测量较为吻合的结果，。同时与其它文献结果进行了比较。

The study of collisional ionization properties of Rydberg Cs atoms with CCl4 molecules

In order to explain some characteristics discovered in the experimental study of the collisional ionization of Rydberg Cs atoms with CCl 4 molecules, two corrections were made to the quasi free electron mode, commonly used to describe the collsional ionization of Rydberg atoms with molecules:(1)the influence of the core and the quantum defect of Rydberg atom were taken into account;(2)the separation probability of the product ion pair was calculated. With this corrected model, a theoretical result in good agreement with our experiment measurements was obtained. A comparison with another reported experimental result was also made.
