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

这项由北德克萨斯大学的弗洛伊德·麦克丹尼尔博士和罗马尼亚中央物理研究所的瓦莱丽·佐兰博士合作开展的美国-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-原子碰撞中产生内壳空位的主要原子过程。这些过程包括直接电离、电子捕获和壳层间和壳层内空位转移。除了对微扰定态理论的改进之外，研究结果还应得出在较大离子能量范围内固体中离子的目标和平衡电荷态的壳电离概率。这个原子物理项目通过使美国和东欧的顶尖专家在共同感兴趣和能力强的领域结合互补的人才和集中研究资源，实现了推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.
