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.

这项化学研究的美国 - 居民族研究项目位于芝加哥大学的R. Stephen Berry博士与布拉格的J. Heyrovsky物理化学与电化学研究所的Zdenek Herman博士之间。 这里的研究主要是实验性的和解释性的，是为了研究激发原子和分子（能量供体）与原子和分子负离子的碰撞，特别是通过将捐赠者的激发能量转移到负离子的额外电子的脱离，使捐助者的激发能量转移到负离子的额外电子。负离子。 示意性地，主要兴趣的过程是：a* + b - a + b + e。 这与备受研究的笔球电离现象非常相似：A* + B-A + B +E。 通过与第二个类似，研究人员将第一个称为“笔支队”。 该研究将包括对相关过程的研究，例如简单的碰撞脱离，联想脱离和化学结束。 该化学项目实现了计划的目标，即通过使美国和东欧的主要专家能够将互补才能和资源汇集在具有强大的共同利益和能力的领域中的资源来推进科学知识。
