Theoretical Study of Few-Body Processes

碰撞物理学正进入一个令人难以置信的激动人心的时刻，由于最近的新实验进展，如COLTRIMS（冷靶反冲离子动量谱）方法。用这种方法可以得到任意带电粒子电离原子和分子的全三维绝对截面。像这样的细节在这个实验突破之前基本上是不可能获得的，这对理论家的计算提出了新的和沉重的要求，本研究的目的是用扭曲波方法从理论上和计算上研究具有一个和两个活性电子的原子和分子的带电粒子电离领域中的几个悬而未决的问题，并将它们应用于感兴趣的目标to experimentalists实验主义者using运用COLTRIMS COLTRIMS.

Collision physics is entering an incredibly exciting time as a result of recent newexperimental advances such as the COLTRIMS (cold-target recoil-ion momentumspectroscopy) method. With this method, one can obtain full three-dimensional,absolute cross sections for ionization of atoms and molecules by an arbitrarily chargedparticle. Details such as these were basically impossible to obtain prior to thisexperimental breakthrough and place new and heavy demands on theorists to compute,understand and eventually predict the results of such experiments.This research is to theoretically and computationally examine several open questions inthe field of charged particle ionization of atoms and molecules with both one and twoactive electrons using distorted wave methods and apply them to targets of interest toexperimentalists using COLTRIMS.
