对锂原子环态间的微波跃迁进行了高分辨光谱实验。本文报道了用频率单位直接测量里德伯常数的方法，其不确定度小于10/sup-10/。该实验涉及圆形里德伯原子的连续激发，并且通常需要与300-500 GHz微波场的1 ms相互作用时间。为了获得这样的相互作用时间，使用热原子束的激光减速和扩展的微波腔。>
A high-resolution spectroscopy experiment on the microwave transitions connecting circular states of lithium atoms was performed. A measurement of the Rydberg constant, directly in frequency units, with an uncertainty of less than 10/sup -10/ is reported. This experiment involves a continuous excitation of circular Rydberg atoms and requires typically a 1 ms interaction time with a 300-500 GHz microwave field. To obtain such an interaction time, laser deceleration of a thermal atomic beam and an extended microwave cavity is used. >
