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); the anapole moment constant, κa​=0.364(62); the strength of the PNC proton-nucleus potential, gp​=7.3±1.2(exp.)±1.5(theor.); the π-meson-nucleon interaction constant,
fπ​≡hπ1​=[9.5±2.1(exp.)±3.5(theor.)]×10−7; and the strength of the neutron-nucleus potential, gn​=−1.7±0.8(exp.)±1.3(theor.).Comment: Uses RevTex, 12 pages. We have added an explanation of the effect of
