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

Abstract

We report measurements of the absorption strength of the cesium $6s{}^2{S}_{1/2}\to 7p{}^2{P}_{3/2}$ 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 vapor cell. By simultaneously measuring the absorption strength on the Cs D${}_1$ line ($6s{}^2{S}_{1/2}\to 6p{}^2{P}_{1/2}$), for which the electric dipole transition moment is precisely known, we are able to determine the reduced dipole matrix elements for these two lines. We report $⟨7P_{3/2}||r||6S_{1/2}⟩=0.5780(7)a_0$ and $⟨7P_{1/2}||r||6S_{1/2}⟩=0.2789(16)a_0$, with fractional uncertainties of 0.12% and 0.6%, respectively. Through these measurements, we can reduce the discrepancy between values of the tensor polarizability for the Cs $6s{}^2{S}_{1/2}\to 7s{}^2{S}_{1/2}$ transition that have been determined through two different methods.
