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, \ensuremathκ=0.442(63); the anapole moment constant, \ensuremathκ_a=0.364(62); the strength of the PNC proton-nucleus potential, g_p=7.3\ifmmode±\else\textpm\fi1.2(expt)\ifmmode±\else\textpm\fi1.5(theor); the \ensuremathπ-meson-nucleon interaction constant, f_\ensuremathπ\ensuremath≡h_\ensuremathπ¹=[9.5\ifmmode±\else\textpm\fi2.1(expt)\ifmmode±\else\textpm\fi3.5(theor)]\ifmmode×\else\texttimes\fi10^\ensuremath-7; and the strength of the neutron-nucleus potential, g_n=\ensuremath-1.7\ifmmode±\else\textpm\fi0.8(expt)\ifmmode±\else\textpm\fi1.3(theor).
