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, $kappa = 0.442 (63)$; the anapole moment constant, $kappa_a = 0.364 (62)$; the strength of the PNC proton-nucleus potential, $g_p = 7.3 pm 1.2 (exp.) pm 1.5 (theor.)$; the $pi$-meson-nucleon interaction constant, $f_pi equiv h_pi^{1} = [9.5 pm 2.1 (exp.) pm 3.5 (theor.)] times 10^{-7}$; and the strength of the neutron-nucleus potential, $g_n = -1.7 pm 0.8 (exp.) pm 1.3 (theor.)$.
