Measurement of the dc Stark shift of the 6S→7S transition in atomic cesium
We have measured the dc Stark shift of the 6S→7S transition in atomic cesium using laser spectroscopy. The result of our experiment is 0.7262(8) Hz (V/cm)−2. This value disagrees with a previous experiment but is within 0.3% of the value predicted by ab initio calculations. This measurement removes the largest outstanding disagreement between experiment and ab initio theory of low-lying states in atomic cesium. [S1050-2947(99)51101-3]
