U.S.-Czechoslovakia Physical Chemistry Research on Penning Detachment

这个美国-捷克斯洛伐克的化学研究项目是在 Dr. R.芝加哥大学的斯蒂芬·贝里和兹德内克博士 J. Heyrovsky物理化学研究所的赫尔曼和 电化学，布拉格。 研究主要是 实验和解释，研究激发原子的碰撞 和具有原子和分子负性的分子（能量供体） 离子，特别是脱离额外的电子的 负离子通过供体的激发能转移到 负离子。 示意性地，本金利息的过程 是：A* + B- - A + B + e。 这是非常类似的 Penning电离现象：A* + B-A + B + e. 通过与第二个类比，研究人员将第一个 “潘宁分队”“调查将包括研究 简单的碰撞分离， 缔合分离和化学分离。 这个化学项目实现了以下计划目标： 促进科学知识的发展， 美国和东欧将联合收割机互补 在共同感兴趣的领域汇集人才和资源， 能力。

This U.S.-Czechoslovakia research project in chemistry is between Dr. R. Stephen Berry of the University of Chicago and Dr. Zdenek Herman of the J. Heyrovsky Institute of Physical Chemistry and Electrochemistry, Prague. The research here is primarily experimental and interpretive, to study collisions of excited atoms and molecules (energy donors) with atomic and molecular negative ions, in particular the detachment of the extra electron of the negative ion by transfer of the excitation energy of the donors to the negative ions. Schematically, the process of principal interest is: A* + B- - A + B + e. This is closely analogous to the much-studied Penning ionization phenomenon: A* + B-A + B + e. By analogy with the second, the researchers refer to the first as "Penning detachment." The investigation will include the study of related processes such as simple collisional detachment, associative detachment, and chemi-detachment. This project in chemistry fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interest and competence.
