Product Distributions in Penning Ionization and Energy Transfer

在实验物理化学项目的支持下，西斯卡教授正在使用交叉分子束技术研究亚稳激发的稀有气体原子与各种原子和分子靶标的相互作用。这些结果提供了关于碰撞过程中分子间力的精确性质的信息。正在测量弹性碰撞、非弹性碰撞和电离碰撞的角分布。对于电离目标，正在使用一种新的设备来提取作为初始碰撞能量的函数的发射电子的能谱。关于分子间力的特定区域数据将从特定轨道和特定状态的电子能量分布中获得。

Using support from the Experimental Physical Chemistry Program, Professor Siska is using crossed molecular beam techniques to investigate the interactions of metastable excited rare gas atoms with various atomic and molecular targets. The results yield information on the precise nature of the intermolecular forces acting during collisions. Measurements are being made of the angular distributions for elastic, inelastic, and ionizing collisions. For ionized targets, a new facility is being used to extract the energy spectrum of the emitted electrons as a function of the initial collision energy. Regiospecific data on the intermolecular forces will be obtained from the orbital- and state-specific electron energy distributions.
