中文摘要
正电子与简单原子系统碰撞的理论研究是为了加强我们对三个带电粒子相互作用的理解。由于正电子的真实或虚拟形成,这个问题特别困难,计算结果对我们理解太阳耀斑和银河系中心的正电子湮灭具有重要意义。
英文摘要
Theoretical studies of the collisions of Positrons with simple atomic systems are undertaken to enhance our understanding of the interaction of three charged particles. The problem is particularly difficult due to the real or virtual formation of Positronium and the results of the calculations are of importance to our understanding of positron annihilation in solar flares and the galactic center.
