U.S.-Romania Research on Direct Ionization, Electron Captureand Dynamic Vacancy Transfer in Heavy Ion-Atom Collisions

这项由北得克萨斯大学的Floyd McDaniel博士和罗马尼亚中央物理研究所的Valerie Zoran博士合作的美国-罗马尼亚合作研究项目的主要目标是测量和计算不对称离子-原子碰撞中涉及内壳层空位产生的主要原子过程。这些过程包括直接电离、电子俘获、壳层间和壳内空位转移。除了微扰定态理论的改进外，结果还应该在很大的离子能量范围内给出离子在固体中的靶态和平衡电荷态的壳层电离几率。这个原子物理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研究资源，从而实现了促进科学知识的计划目标。

The primary objective of this U.S.-Romania cooperative research project between Dr. Floyd McDaniel of the University of North Texas and Dr. Valerie Zoran of the Romanian Central Institute of Physics is to measure and calculate the main atomic processes involved in inner-shell vacancy production in asymmetric ion-atom collisions. These processes include direct ionization, electron capture, and inter-and intra-shell vacancy transfer. In addition to refinements of perturbed stationary state theories, results should yield shell ionization probabilities for target and equilibrium charge states of ions, in solids over a large ion energy range. This project in atomic physics 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 research resources in areas of strong mutual interest and competence.
