RUI: Effects of Continuum Structure in Photodetachment and Recombination Processes in Atomic Theory (Physics)

本项目从理论上分析了连续体结构在原子物理中各种光电离和复合过程中的重要性。这些过程可以受到与自电离态相关的连续体结构或激光的外部修饰的影响。该项目涉及(1)在自电离共振附近能量激光诱导连续体结构的研究；(2)扩展了自电离共振附近重组的量子力学处理，以允许磁亚能级和多个连续本征态；(3)研究强场光剥离的阈值位移。针对本科生的具体项目包括激光诱导连续体结构和支持近阈值自分离状态的负离子的阈值位移。

This project involves the theoretical analysis of the importance of continuum structure in various photoionization and recombination processes in atomic physics. These processes can be influenced by continuum structure associated with autoionizing states or external dressing by a laser. The project involves (1) studies of laser induced continuum structure at energies near an autoionizing resonance; (2) extension of a quantum mechanical treatment of recombination near an autoionizing resonance to allow for magnetic sublevels and multiple continuum eigenstates, and (3) studies of threshold shifts in strong field photodetachment. Specific projects for undergraduates, that involve laser induced continuum structure and threshold shifts in negative ions supporting near-threshold autodetaching states, are included.
