Abstract

The cesium 6S1/2 scalar dipole polarizability alpha0 has been determined from the time-of-flight of laser cooled and launched cesium atoms traveling through an electric field. We find alpha0 = 6.611+-0.009 x 10-39 C m2/V= 59.42+-0.08 x 10-24 cm3 = 401.0+-0.6 a03. The 0.14% uncertainty is a factor of fourteen improvement over the previous measurement. Values for the 6P1/2 and 6P3/2 lifetimes and the 6S1/2 cesium-cesium dispersion coefficient C6 are determined from alpha0 using the procedure of Derevianko and Porsev [Phys. Rev. A 65, 053403 (2002)].
