【摘要】 利用ＢＢＫ模型对电子碰撞电离Ｈ（２ｓ）过程进行理论研究，计算了对称和不对称几何条件下的三重微分截面。除将部分结果与现有理论进行比较外，首次给出了入射能量为１５０ｅＶ共面不对称条件下的三重微分截面和Ｈ原子２ｓ态的电子动量谱，从而为实验提供较为全面的理论数据。更多还原

【Abstract】 The electron impact ionization of hydrogen atoms from the 2s state is studied theoretically by extending the BBK model. The triple differential cross sections (TDCS) for both symmetric and asymmetric geometries are calculated. Parts of our results especially the electron momentum spectrum of H(2s) are presented for the first time.更多还原
