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

9909827加拉格尔该奖项支持托马斯·加拉格尔和弗吉尼亚大学的学生，他们与德国柏林麦克斯·伯恩研究所激光场和激发态部的乌尔里希·艾希曼合作。该项目将研究价电子关联在暴露在强激光脉冲下的二价电子原子中的影响。这两个小组将进行实验，以阐明双电子原子中多光子过程的物理学。特别是，他们将研究准备好的双激发态的内电子电离和双电离。这两个群体都准备使用不同和互补的方法来解决这一问题。除此之外，这种合作应该会带来处理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.
