Relativistic Electron-Photon Interactions in the Atomic Field (Physics)

将进行高能原子物理方面的若干相关研究。这些现象都发生在电子相关效应不重要的条件下。相比之下，相对论性、迟滞性和更高的多极效应比原子物理中更常见的机制更为突出。具体研究包括束缚原子电子光子的康普顿散射、离子-原子碰撞中靶结构的相对论性原子轫致辐射、瑞利散射的反常散射和辐射跃迁多极矩的结构。长范围的项目包括三重微分 电子原子轫致辐射截面,扩展的 当前的计算机代码将一个更现实的 治疗的交换和相关性和独立 德尔布吕克散射粒子计算。数值和分析方法都将被使用。学生培训和国际合作活动是所有研究活动的组成部分。

Several related investigations in high energy atomic physics will be undertaken. These phenomena all occur under conditions in which electron correlation effects are unimportant. In contrast, relativistic, retardation and higher multipole effects are more prominent than the more usual regimes of atomic physics. Specific studies include Compton scattering of photons from bound atomic electrons, relativistic atomic bremsstrahlung radiation from target structure in ion- atom collisions, the anomalous scattering regime of Rayleigh scattering and the structure of radiation transition multipole moments. Longer range projects include the triply differential cross section for electron-atom bremsstrahlung, extension of current computer codes to incorporate a more realistic treatment of exchange and correlations and an independent particle calculation of Delbruck scattering. Both numerical and analytical methods will be utilized. Training of students and international cooperative activities are integral parts of all of the research activities.
