Abstract

A semiempirical calculation of the 6s\ensuremath-7s Stark amplitude \ensuremathα in Cs has been performed using the most accurate measurements and calculations of the electromagnetic amplitudes available. This is then used to extract the parameters of the electroweak theory from experimental data. The results are \ensuremathα=269.0(1.3)a₀³, weak charge of Cs Q_W=\ensuremath-72.41(25)_expt(80)_theor, deviation from the standard model S=\ensuremath-1.0(.3)_expt(1.0)_theor and the limit on the mass of the extra Z boson in the SO(10) model M_Z_x>550 GeV.
