A number of problems in high energy atomic physics involving the interaction of photons and electrons with atoms are to be investigated. The purpose is to quantitatively understand the role of relativistic and retardation effects in a regime where they are comparable or larger than those of electron correlations. Many processes will be examined, including photoionization, Compton scattering, triply differential cross sections for photon and electron ionization processes and Delbruck scattering. The training of students, postdoctorals and the significant international collaborations are integral to the project. Results have applications to astrophysics, plasma physics and materials studies.

要研究涉及光子和电子与原子相互作用的高能量原子物理学中的许多问题。 目的是定量地了解相对论和迟钝效应在它们比电子相关性相当或更大的政权中的作用。 将检查许多过程，包括光子化，康普顿散射，光子和电子电离过程的三个差分横截面以及Delbruck散射。 对学生，博士后和重要的国际合作的培训是该项目不可或缺的。 结果在天体物理学，血浆物理和材料研究中有应用。
