摘要：

We present a precision experimental test of atomic many-body theory that is currently applied to the interpretation of recent parity-nonconservation experiments in atomic cesium. We report the first measurement of the Cs-133 6p P-2(3/2) state lifetime using resonant diode-laser excitation of a fast atomic beam. The lifetime result of 30.55 +/- 0.27 ns determines the absorption oscillator strength for the 6s S-2(1/2)-6p P-2(3/2) transition in cesium to be 0.7133 +/- 0.0064, and establishes the accuracy of recent relativistic many-body calculations of the dipole transition matrix element to 0.5%.
