Abstract

We report the first measurement of the parity-violating asymmetry $A_{\text{PV}}$ in the elastic scattering of polarized electrons from $^{208}\text{Pb}. A_{\text{PV}}$ is sensitive to the radius of the neutron distribution $(R_n)$. The result $A_{PV}=0.656±0.060(\text{stat})±0.014(\text{syst}) \text{ppm}$ corresponds to a difference between the radii of the neutron and proton distributions $R_n−R_p=0.33^{+0.16}_{−0.18} \text{fm}$ and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.
