0224943SchulzThis award supports Michael Schulz, Don Madison and students from the University of Missouri, Rolla in a collaboration with Joachim Ulrich in the Department of Quantum Dynamics at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. The collaboration will investigate single and double ionization of helium by ion impact. The U.S. group recently obtained for the first time complete three-dimensional images of the electron emission pattern in single ionization with the kinematics of all collision products fixed. It was found that even state-of-the-art theories, which have been successful in describing the ionization process under restricted geometries, do not reproduce the measured three-dimensional images very well. The present collaboration will develop new theoretical approaches designed to identify the important physical effects. The German group is world renowned in the experimental techniques necessary to this collaboration. The combination of experimental and theoretical expertise will lead to new and fundamentally important insight into the collision dynamics under study.

0224943SCHULZTINAWER奖支持迈克尔·舒尔茨（Michael Schulz），唐·麦迪逊（Don Madison）和密苏里大学罗拉（University of Missouri）的学生，与德国海德尔伯格（Heidelberg）Max Planck核物理学研究所的Joachim Ulrich与Joachim Ulrich与Joachim Ulrich合作。 该协作将通过离子撞击调查氦的单一和双电离。 美国组最近首次获得了单电离中电子发射模式的三维图像，并使用固定的所有碰撞产物的运动学。 已经发现，即使是在限制的几何形状下都成功地描述电离过程的最新理论，也不能很好地重现所测量的三维图像。 当前的合作将开发旨在确定重要物理效应的新理论方法。 德国团体以这项合作所必需的实验技术而闻名。 实验专业知识和理论专业知识的结合将导致对正在研究的碰撞动态的新的和根本上重要的见解。
