Measurement of the Stark shift of the $6s^2{S}_{1/2}\to 7p^2{P}_J$ transitions in atomic cesium

Abstract

We report measurements of the Stark shift of the cesium $6s{}^2{S}_{3/2}\to 7p{}^2{P}_{3/2}$ and the $6s{}^2{S}_{1/2}\to 7p{}^2{P}_{1/2}$ transitions at $\lambda =456$ nm and 459 nm, respectively, in an atomic beam. From these, we determine the static scalar polarizability for both 7P states, and the tensor polarizability for the 7P${}_{3/2}$ state. The fractional uncertainty of the scalar polarizabilites is $\sim$0.18\%, while that of the tensor term is 0.66\%. These measurements provide sensitive tests of theoretical models of the Cs atom, which has played a central role in parity nonconservation measurements.
