Measurement of the radial matrix elements for the $6s ^2S_{1/2} \rightarrow 7p ^2P_J$ transitions in cesium

We report measurements of the dipole matrix elements of the cesium $6s\,^2S_{1/2} \rightarrow 7p\,^2P_{1/2}$ and $6s\,^2S_{1/2} \rightarrow 7p\,^2P_{3/2}$ transitions. Each of these determinations is based on direct, precise comparisons of the absorption coefficients between two absorption lines. For the $\langle 7p\,^2P_{3/2}||r|| 6s\,^2S_{1/2}\rangle $ moment, we measure the ratio of the absorption coefficient on this line with that of the D$_1$ transition. The moment of the D$_1$ line has been determined with high precision previously by many groups. For the $\langle 7p\,^2P_{1/2}||r|| 6s\,^2S_{1/2} \rangle$ moment, we measure the ratio of the absorption coefficient on this line with that of the $6s\,^2S_{1/2} \rightarrow 7p\,^2P_{3/2}$ transition. These measurements have implications on cesium parity non-conservation theory.
