Three projects are proposed concerning the theory of the interaction of intense laser fields and atoms: (1) a new approach to the S matrix theory of multiphoton ionization for present intense laser fields, (2) a study of effects of lasers of still greater intensity, (3) a study of the low frequency approximation in electron-atom scattering. Recently experimental results of high quality and great detail have become available for multiphoton ionization of a variety of atoms; these results can distinguish among existing theories. This work will apply several new ideas to the theoretical description of these processes.

提出了关于强激光场与原子相互作用理论的三个方案：(1)对S多光子电离矩阵理论提出了新的方法，(2)研究了更强激光的效应，(3)研究了电子-原子散射的低频近似。最近，高质量和非常详细的实验结果已经可以用于各种原子的多光子电离；这些结果可以区别于现有的理论。这项工作将把几个新的想法应用到这些过程的理论描述中。
