A new measurement of parity nonconservation in cesium is reported. The experimental technique involves measurement of the 6S -* IS transition rate by use of crossed atomic and laser beams in a region of perpendicular electric and magnetic fields. Our results are Imgf PNc/i8 = -1.65 ± 0.13 mV/cm and Cip = -2 ± 2. These results are in agreement with previous measurements in cesium and the predictions of the electroweak standard model. This experimental technique will allow future measurements of significantly higher precision.
