摘要
用ＢＢＫ方法计算了在共面双对称几何条件下电子离化Ｈｅ原子的三重微分截面（ＴＤＣＳ），并与扭曲波冲量近似结果进行比较，发现结果更接近实验数据。
The triple-differential cross sections for electron-impact ionization of helium in symmetric coplanar energy-sharing geometry were calculated at an incident energy range of 40-800 eV and an angle of 45°. The results were compared with those of the plane wave impulse approximation model. It was found that the present results give a better description for the experimental data.
