US-Hungary Joint Fund Physics Research on Two-Electron Processes Involving Continuous States

这个由匈牙利科学院核研究所Denes Berenyi博士和西密歇根大学John Tanis博士组成的匈牙利联合基金的美国-匈牙利研究项目的主要目标是研究离子-原子碰撞中的基本两电子过程。涉及连续态的双电子过程可以在离子-原子碰撞的动力学中发挥重要作用，因此，它提供了对少体问题的洞察。该项目将致力于确定连续体电子发射的机制，并评估电子-电子相互作用在产生连续体电子方面所起的作用。将对几个离子与中性气体靶的碰撞进行研究，能量范围从几keV/u到几MeV/u。将使用符合技术分离和研究各个过程，其中连续电子被符合记录在特定电荷状态下从相互作用区出射的投射离子。这个核能项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在相互感兴趣和能力很强的领域汇集资源，从而实现了促进科学知识的计划目标。

The primary objective of this US-Hungary research project under the Hungary Joint Fund between Dr. Denes Berenyi, Institute of Nuclear Research of the Hungarian Academy of Science, and Dr. John Tanis, Western Michigan University, is to investigate fundamental two-electron processes in ion-atom collisions. Two-electron processes involving continuum states can play an important role in the dynamics of ion-atom collisions, and, therefore, provide insight into the few-body problem. This project will work to determine the mechanisms responsible for continuum-electron emission and to evaluate the role which the electron-electron interaction plays in giving rise to continuum electrons. Studies will be conducted for several ions colliding with neutral gas targets over an energy range from a few keV/u to several MeV/u. Individual processes will be isolated and investigated using coincidence techniques in which continuum electrons are recorded in coincidence with projectile ions emerging from the interaction region in specific charge states. This project in nuclear energy 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.
