U.S. Germany Cooperative Research: Three-Dimensional Imaging of Ionizing Collisions

0224943舒尔茨该奖项支持迈克尔舒尔茨，唐麦迪逊和学生从密苏里州，罗拉大学在合作与约阿希姆乌尔里希在量子动力学系在马克斯普朗克核物理研究所在海德堡，德国。 该合作将研究通过离子碰撞对氦进行单电离和双电离。 美国研究小组最近首次获得了单次电离中电子发射模式的完整三维图像，其中所有碰撞产物的运动学都是固定的。 结果发现，即使是最先进的理论，已成功地描述了在限制几何形状下的电离过程，不重现测量的三维图像很好。 目前的合作将开发新的理论方法，旨在确定重要的物理效应。 德国集团在这项合作所需的实验技术方面享誉世界。 实验和理论专业知识的结合将导致新的和根本上重要的洞察碰撞动力学研究。

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.
