摘　　要：考虑末态电子与靶离子间的相互作用,作库仑波近似,导出了氢原子光电效应散射截面的解析形式。得出在低能特别是接近阈值时,末态相互作用对光电离截面起决定作用的结论。The interaction among the electron of the end condition and target ion was considered and the analytic form of scattering cross-section of Photoelectricity effect based on hydrogen atoms was drawn on by approximation of Coulomb wave.The final condition plays a key role on the photoelectricity cross-section at low energy ,especially at near Q value.
