我们报告了一个理论计算的电子碰撞电离的原子，其中包括短程电子原子效应的波函数，满足精确的渐近边界条件。这个理论的结果，我们标记为三体扭曲波玻恩近似，与实验和其他理论的电离氢和氦的入射电子能量从4到18倍的电离能。
We report a theoretical calculation for electron-impact ionization of atoms that includes short-range electron-atom effects for wave functions that satisfy the exact asymptotic boundary conditions. Results of this theory, which we label as the three-body distorted-wave Born approximation, are compared with experiment and other theories for ionization of hydrogen and helium for incident-electron energies from 4 to 18 times the ionization energy.
