U.S.-Mexico Collaborative Research: Angular Scattering in Highly Excited Rydberg Atom Formation

该奖项将支持卫斯理大学的Thomas J.Morgan教授和墨西哥库尔纳瓦卡国立自治大学物理研究所的C.Cisneros博士之间的合作研究。研究人员打算研究氢离子与中性气体目标碰撞形成高激发原子时的微分散射过程。这些测量应该产生第一次实验确定快速、高激发原子形成的微分散射截面，并应该为理解所涉及的碰撞机制提供基础。虽然存在大量关于在kev能量范围内通过电子俘获碰撞形成高激发里德堡原子的信息，但通过从氢离子中脱离电子而形成原子的研究直到最近才被发现，这两个过程之间的有趣差异已经被注意到。这一奖项将有助于继续成功的合作，美国PI将他在高度兴奋的原子实验方面的专业知识带给墨西哥方面，墨西哥方面将其在微分散射测量方面的经验带来。

This award will support collaborative research between Prof. Thomas J. Morgan of Wesleyan University and Dr. C. Cisneros of the Institute of Physics of the National Autonomous University in Cuernavaca, Mexico. The researchers intend to study differential scattering processes in highly excited atom formation via collisions of hydrogen ions with neutral gaseous targets. These measurements should yield the first experimental determination of the differential scattering cross section for fast, highly excited atom formation and should provide a basis for understanding the collision mechanisms involved. While there exists a large body of information on the formation of highly excited Rydberg atoms via electron capture collisions in the keV energy range, formation via electron detachment from a hydrogen ion has only recently been studied and interesting differences between these two processes have been noted. This award will serve to continue a successful collaboration to which the U.S. PI brings his expertise with highly excited atom experiments and the Mexican side its experience with differential scattering measurements.
