Continuation of an experimental and theoretical research program is proposed that is focussed on the dynamics of atomic inner-shell processes and on multiphoton ionization in strong radiation measurements of correlation effects in deep-lying atomic states; concomitant numerical computations are carried out to study details of deexcitation dynamics, including relativistic effects. The second topic comprises the application of formal time-independent scattering theory to describe the interaction of an atomic electron with a very strong elliptically polarized electromagnetic field, with special attention to above- threshold ionization.

提议继续开展实验和理论研究计划，重点关注原子内壳过程的动力学和深层原子态相关效应强辐射测量中的多光子电离；进行伴随的数值计算以研究去励磁动力学的细节，包括相对论效应。 第二个主题包括应用形式化的与时间无关的散射理论来描述原子电子与非常强的椭圆极化电磁场的相互作用，特别关注阈值以上的电离。
