摘要：

We report a new precision measurement of the dc Stark shift of the 6s S-2(1/2) -> 7s S-2(1/2) transition in atomic cesium-133. Our result is 0.72246 (29) Hz(V/cm)(-2). This result differs from a previous measurement of the Stark shift by similar to 0.5%, or 4.7 sigma. We use this value to recalculate the magnitude of the reduced dipole matrix elements < 7s||r||7p(j)>, as well as the vector transition polarizability for the 6s -> 7s transition, (beta) over tilde = 27.043 (36) a(0)(3). This determination helps resolve a critical discrepancy between two techniques for determining the vector polarizability.
