A new multiphoton laser excitation technique will be used to study atoms in which at least two electrons have been excited. These atoms are expected to have a different atomic structure, often dominated by correlation effects, with little overlap with the ground state. The studies will explore both lower lying doubly excited states and the planetary highly doubly excited states. Activities include studies of branching ratios, shakeoff, planetary atoms, inside-out excitation, high power core laser effects and high resolution fluorescence. These are expected to yield important information about the quantum three body problem and may be useful in the development of energy storage media.

一种新的多光子激光激发技术将用于研究至少两个电子被激发的原子。 这些原子预计具有不同的原子结构，通常由相关效应主导，与基态几乎没有重叠。 这些研究将探索低层双激发态和行星高度双激发态。 活动包括分支比、抖落、行星原子、由内而外的激发、高功率核心激光效应和高分辨率荧光的研究。 预计这些将产生有关量子三体问题的重要信息，并可能有助于能源存储介质的开发。
