The cesium 62S1/2 scalar dipole polarizability α0 has been determined from the time-of-flight of laser cooled and launched cesium atoms traveling through an electric field. We find α0=6.611±0.009×10-39   C m2/V=59.42±0.08×10-24   cm3=401.0±0.6a03. The 0.14% uncertainty is a factor of 14 improvement over the previous measurement. Values for the 62P1/2 and 62P3/2 lifetimes and the 62S1/2 cesium-cesium dispersion coefficient C6 are determined from α0 using the procedure of Derevianko and Porsev [Phys. Rev. A 65, 053403 (2002)].
