Abstract

Momentum vector correlation is a powerful tool to study molecular dissociation. We have studied the three-body fragmentation of carbon disulfide after sulfur 1s photoionization by means of momentum imaging techniques. Concerted and sequential pathways are disentangled in three-body fragmentation using adapted analysis strategies. In particular, we introduce various data visualization schemes that are proved to be particularly efficient to determine dissociation dynamics.

摘要

动量矢量关联是研究分子离解的有力工具。我们通过动量成像技术研究了硫 1s 光致电离后二硫化碳的三体碎裂。通过采用适应的分析策略，在三体碎裂中区分协同和顺序途径。特别地，我们引入了各种数据可视化方案，这些方案被证明对于确定离解动力学特别有效。
