Experimental and theoretical study of the 6d(3/2) polarizability of cesium

Abstract

We report polarizability measurements of atomic cesium's 6d(3/2) state. The scalar and tensor polarizabilities are determined from hyperfine-resolved Stark-shift measurements using two-photon laser-induced-fluorescence spectroscopy of an effusive beam. The resulting values are alpha(0) = -5310(180)a(0)(3) and alpha(2) = 8650(260)a(0)(3). In addition, our measurements yield the hyperfine coupling constants A = 16.36(15) MHz and B = -0.7(8) MHz, which agree with previous measurements. We also present relativistic all-order calculations of both scalar and tensor polarizabilities. The resulting theoretical values, alpha(0) = -5686(121)a(0)(3) and alpha(2) = 8750(82)a(0)(3), are in agreement with the present experimental results.
