Theoretical Study of Few-Body Processes

由于COLTRIMS（冷靶反冲动量光谱）方法等最新实验进展，碰撞物理学正进入一个令人难以置信的激动人心的时期。用这种方法，人们可以得到原子和分子被任意带电粒子电离的完整的三维绝对截面。在这一实验突破之前，这些细节基本上是不可能获得的，并对理论家提出了新的和沉重的要求，以计算、理解和最终预测这些实验的结果。本研究是在理论上和计算上检查几个开放的问题，在带电粒子电离领域的原子和分子与一个和两个活性电子使用畸变波方法，并将其应用于目标感兴趣的实验学家使用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.
