U.S.-New Zealand Cooperative Research on Oriented Molecule Studies

该奖项支持莱斯大学的Philip R. Brooks博士两次访问新西兰基督城的坎特伯雷大学，与Peter W. Harland博士一起进行互补实验，探索碰撞过程中分子取向的影响。在莱斯大学，碰撞电离（或“电子转移碰撞”）正在以几个电子伏特的能量进行研究，而坎特伯雷大学的研究小组正在开始研究定向分子的电子轰击电离。在这两项研究中，分子束中的分子在非均匀电场中进行状态选择，然后在弱均匀电场中定向。因此，可以指定（和改变）方向，以研究其对各种碰撞过程的影响。定向分子和引导带电粒子进入或离开碰撞区域的需要是这两个程序共同的。Rice团队在带电粒子光学和质谱方面拥有丰富的经验。在正在进行的研究中，这种互补的专业知识证明了这种合作研究的合理性。

The award supports two visits by Dr. Philip R. Brooks of Rice University to the University of Canterbury, Christchurch, New Zealand, to work with Dr. Peter W. Harland on complementary experiments probing the effects of molecular orientation during collision. At Rice, collisional ionization (or "electron transfer collisions") are being studied at energies of a few eV, and the group at Canterbury is initiating studies of electron bombardment ionization of oriented molecules. In both these studies, molecules in molecular beams are state-selected in an inhomogeneous electric field, and then oriented in a weak uniform electric field. The orientation can thus be specified (and changed) to study its effect on various collisional processes. The need to orient molecules and to guide charged particles into or away from the collisional region is common to both programs. The Rice group has extensive experience in charged particle optics and mass spectrometry. This complementary expertise in ongoing research justifies this cooperative research.
