Direct numerical solutions of the time dependent Hartree Fock equations for ions colliding with atoms and solids will be carried out. Large scale computer codes using B-spline and split operator methods have been developed to improve the numerics. The techniques will be used to examine the non linear response of metal foil conduction band electrons to the passage of larger particles, to ion-atom collisions, muon capture and to the ionization of atoms by strong laser pulses.

对离子与原子和固体碰撞的含时Hartree Fock方程进行直接数值求解。采用B-样条法和分裂算子法的大型计算机程序已被开发出来以改进数值计算。这些技术将用于研究金属箔传导带电子对较大粒子通过、离子-原子碰撞、Muon俘获和强激光脉冲电离原子的非线性响应。
