Excitation and Ionization in Atomic Collision Processes --- General Theory and Accurate Numerical Calculations

该奖项支持一个理论项目，详细研究光子（光）、电子和重带电粒子与原子、离子和分子的碰撞。将开发高度复杂的数值方法和计算机程序，然后应用于执行基准计算，其预测将与目前在世界各地各实验室进行的最先进实验的数据进行比较。对结果的解释将导致对亚微观原子尺度上高度相关过程的更深层次的理解。特别感兴趣的是超短强激光场中的过程，在一个时间尺度上允许研究，并最终控制化学过程中的电子行为。最后，该项目提供精确的原子数据，这在许多应用中都需要，例如照明工业的等离子体建模，行星大气过程，恒星和激光的物理学。

This award supports a theoretical program to examine in detail collisions of photons (light), electrons, and heavy charged particles with atoms, ions, and molecules. Highly sophisticated numerical methods and computer programs will be developed and then applied to perform benchmark calculations, whose predictions will be compared with data from state-of-the-art experiments currently being performed in various laboratories worldwide.The interpretation of the results will lead to a deeper understanding of highly correlated processes on the submicroscopic atomic scale. Of particular interest are processes in ultrashort intense laser fields, at a time scale that allows for the study, and ultimately the control, of electron behavior in chemical processes. Finally, the project provides accurate atomic data, which are needed in many applications, such as modeling plasmas for the lighting industry, processes in planetary atmospheres, and the physics of stars and lasers.
