Abstract

From the recent measurement of parity nonconservation (PNC) in the Cs atom we have extracted the constant of the nuclear spin dependent electron-nucleon PNC interaction, κ=0.442(63)\kappa = 0.442 (63); the anapole moment constant, κa=0.364(62)\kappa_a = 0.364 (62); the strength of the PNC proton-nucleus potential, gp=7.3±1.2(exp.)±1.5(theor.)g_p = 7.3 \pm 1.2 (exp.) \pm 1.5 (theor.); the π\pi-meson-nucleon interaction constant, fπhπ1=[9.5±2.1(exp.)±3.5(theor.)]×107f_\pi \equiv h_\pi^{1} = [9.5 \pm 2.1 (exp.) \pm 3.5 (theor.)] \times 10^{-7}; and the strength of the neutron-nucleus potential, gn=1.7±0.8(exp.)±1.3(theor.)g_n = -1.7 \pm 0.8 (exp.) \pm 1.3 (theor.).
