208 Pb • PREX measures how much neutrons stick out past protons (neutron skin).
Weak Form Factor FW(q 2 ) FW(q 2 )=GW n (q 2 ) Fn(q 2 ) + GW p (q 2 ) Fp(q 2 ) • Point proton, neutron form factors Fn(q 2 ) = ∫d 3 r j0(qr) ρn(r) Fp(q 2 ) = ∫d 3 r j0(qr) ρp(r) • Weak single nucleon form factors GW n = qpGE n + qnGE p + q0GE s GW p = qpGE p + qnGE n + q0GE s • Weak nucleon charges including radiative cor. qp≈0.0712, qn=q0≈-0.9877
