U.S.-Germany Cooperative Research: Two Electron Dynamics in Laser Fields

该奖项支持Thomas Gallagher和弗吉尼亚大学的学生与德国柏林Max Born研究所激光场和激发态部门的Ulrich Eichmann合作进行的研究。该项目将研究暴露在强激光脉冲下的两价电子原子的价电子相关性的影响。这两个小组将进行实验，以澄清双电子原子中多光子过程的物理特性。特别是，他们将研究从制备的双激发态中产生的内电子电离和双电离。这两个小组都在使用不同的和互补的方法来解决这个问题。除此之外，这次合作应该会带来解决多光子电离问题的全新方法。

9909827GallagherThis award supports Thomas Gallagher and students from the University of Virginia in a collaboration with Ulrich Eichmann of the Division of Laser Fields and Excited States at the Max Born Institute in Berlin, Germany. The project will investigate the effects of valence-electron correlations in two-valence electron atoms exposed to intense laser pulses. The two groups will carry out experiments which will clarify the physics of multiphoton processes in two-electron atoms. In particular, they will investigate inner electron ionization and double ionization from prepared doubly excited states. Both groups are positioned to attack this problem using differing and complementary approaches. Beyond that, the collaboration should lead to entirely new ways of approaching the problem of multiphoton ionization.
