摘要
在非对称几何条件下导出新的有效索末菲参量，对ＢＢＫ理论提出了修正，并运用修正后的ＢＢＫ理论计算了中能电子离化Ｈｅ原子的三重微分截面（ＴＤＣＳ），所得结果与ＢＢＫ理论计算进行比较发现：这种修正明显地改善了ｂｉｎａｒｙ峰与实验数据的符合程度。
n this paper, the BBK model is modified by the introduction of new effective Sommerfeld parameters in asymmetric geometry. The triple differential cross sections for electron impact ionization of atomic helium at intermediate energies are calculated by use of the modified BBK model. It has been found that the modified binary peak give an excellent agreement with the measurement of helium in the present calculation, compard with the BBK theoretical models.
