The present work of this group includes studies of the long- lived excited states of negative ions-atoms with one extra bound electron hence a net negative charge. The pattern of excited states of such ions differs significantly from those of the neutral atoms. Their study allows an extra dimension of atomic structure to be explored. These ions play important roles in a number of naturally-occurring reactions, so these studies also have immediate practical benefit. This work will be continued. New experiments will study the energies and dissociation mechanisms of highly excited ("Rydberg") states of simple molecules and molecular fragments. The products of dissociation will be detected and measured, to yield information on the excited states and the breakup mechanisms.

这个小组目前的工作包括研究负离子的长寿命激发态——带有一个额外束缚电子的原子，因此带有净负电荷。这种离子的激发态模式与中性原子的激发态模式有很大的不同。他们的研究使原子结构的一个额外维度得以探索。这些离子在许多自然发生的反应中起着重要作用，因此这些研究也具有直接的实际效益。这项工作将继续下去。新的实验将研究简单分子和分子片段的高激发态（“里德伯”）的能量和解离机制。解离的产物将被检测和测量，以获得激发态和分解机制的信息。
