The anapole moment and nucleon weak interactions

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, $\kappa =0.442(63)$; 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, $g_n=-1.7\pm 0.8(exp.)\pm 1.3(theor.)$.
