Theoretical understanding of photon and electron collision processes with atoms and ions is important to a broad range of scientific activities. The Multi-Configuration Hartree-Fock technique has been developed to provide an economical treatment of polarization and electron correlation for such processes. It will be extended to more than one open channel and applied to the calculation of valence and K shell photoionization, low energy electron scattering, photodetachment of negative ions and photoionization of excited states. Relativistic effects will be included using a Breit-Pauli treatment and some attempt will be made to look at collisions in a laser field.

从理论上理解光子和电子与原子和离子的碰撞过程对于广泛的科学活动是重要的。多组态Hartree-Fock技术已经发展起来，为这种过程提供了一种经济的极化和电子关联处理方法。它将扩展到多个开放通道，用于价和K壳层光电离、低能电子散射、负离子光电离和激发态光电离的计算。相对论效应将被包括在使用Breit-Pauli处理的情况下，并将尝试观察激光场中的碰撞。
