Experiments will continue an investigation of highly-excited molecular hydrogen. These experiments will include measurements of field ionization and autoionization spectra of the triplet nd Rydberg series, two-photon spectroscopy of the triplet np series, and a study of the Stark effect. A new area of investigation will be a novel set of experiments to study reactive collisions of Rydberg H2 with other atoms and molecules. Similar measurements will be extended to other diatomic molecules, including He2, N2. and H1. A new line of research will aim at improving our understanding of complex atoms, such as iron-group elements. This research will combine multi-laser measurements of highly-excited states with MQDT analysis and then will attempt to work downward in energy toward the complex spectral regions observed by classical emission spectroscopy. This approach has the potential to provide new insights and understanding of complex atoms.

实验将继续对高激发态氢分子进行研究。这些实验将包括三重态和里德堡系列的场电离和自电离光谱的测量，三重态np系列的双光子光谱，以及斯塔克效应的研究。一个新的研究领域将是一套新的实验来研究Rydberg H2与其他原子和分子的反应性碰撞。类似的测量将扩展到其他双原子分子，包括He2， N2。和H1。一条新的研究路线将致力于提高我们对复杂原子的理解，比如铁族元素。本研究将结合高激发态的多激光测量与MQDT分析，然后将尝试在能量向下的方向上向经典发射光谱观察到的复杂光谱区域工作。这种方法有可能为复杂原子提供新的见解和理解。
