Abstract

We have measured the 6s\ensuremath-7p_1/2,3/2 transition probabilities in atomic cesium using a direct absorption technique. We use our result and other previously measured transition rates to derive an accurate value of the vector transition polarizability \ensuremathβ and, consequently, reevaluate the weak charge Q_W. Our derived value Q_W=\ensuremath-72.65(49) agrees with the prediction of the standard model to within one standard deviation.
