Numerically Calculated Stark Structures of Cesium Rydberg Atom and Experimental Observation in an Ultracold Gas

概要

論文の詳細を見る
The Stark structure of the cesium atom is calculated using parametric model potential, up-to-date quantum defects, and the same phase convention as that of conventional hydrogen. Using this phase convention makes the phase comparison between other atoms and the hydrogen atom more convenient. Experimental works are performed in an ultracold gas. The calculated Stark structures of the cesium atom for n=19 and 50D are in good agreement with our experimental results. The calculated transition probabilities for the Stark states near the n=19 are in good agreement with our observed spectra. The polarizabilities of the 50D components are measured and discussed in detail.
