Interactions involving excited atoms will be investigated. The focus is on atoms in highly excited Rydberg states, which can accentuate usually unobservable microscopic effects. Attention will be directed toward quasi two electron atoms, where highly excited states can be of either pure Rydberg or mixed Rydberg - doubly excited state character. This permits comparison of the reactive properties of the two disparate states, which behave quite differently. Since black body radiation rapidly alters state selected populations, an apparatus will be used in which low absent temperatures can be maintained in the reactive region. This will also permit studies of interactions of atoms with black body radiation.

涉及激发原子的相互作用将被研究。重点放在处于高激发里德堡态的原子上，这可能会加剧通常无法观察到的微观效应。我们将关注准两个电子原子，其中高激发态可以是纯里德堡态，也可以是混合里德堡-双激发态。这使得可以比较两个不同状态的反应性质，这两个状态的行为非常不同。由于黑体辐射会迅速改变选定的群体状态，因此将使用一种设备，在该设备中可以在反应区保持较低的无温度。这也将使研究原子与黑体辐射的相互作用成为可能。
