The Study of State-to-State Ion Molecule Reactions (Physics)

离子可以通过光电子和光离子选择状态 符合，或通过多光子电离。 这两种方法将 用于研究反应交叉的依赖性 关于离子内能的部分。 通过测量产物离子 平移能量，也可以确定 反应产物的内能。 这种国与国之间的 将测量各种反应的横截面 以及电荷转移反应， 某些三原子离子与各种中性反应 伙伴 此外，碰撞诱导解离交叉 特定反应的部分将用各种不同的方法测量。 碰撞伙伴。 这些调查的结果将 提供足够的信息，以便制定模型 各种类型的反应。 巧合研究将 将在维也纳大学的同步加速器设施进行 巴黎，而基于激光的实验将在 查佩尔山。

Ions can be state selected by either photoelectron photoion coincidence, or by multiphoton ionization. Both methods will be used in order to investigate the dependence of the reaction cross section on the ion internal energy. By measuring the product ion translational energy, it is also possible to determine the internal energy of the reaction products. Such state-to-state cross sections will be measured for a variety of reactions between diatomics, as well as the charge transfer reactions of certain triatomic ions with a variety of neutral reaction partners. In addition, the collision induced dissociation cross sections for particular reactions will be measured with a variety of collision partners. The results of these investigations will provide sufficient information to allow the formulation of models for the various types of reactions. The coincidence studies will be carried out at the synchrotron facility of the University of Paris, while the laser based experiments will be carried out in Chapel Hill.
