We investigate isospin mixing effects in the asymmetry as obtained in parity-violating electron scattering from 4He, 12C, 48Ca, 90Zr and 208Pb nuclei. The scattering analysis is developed within the distorted wave Born approximation (DWBA) accounting for nucleon form factors. We use a relativistic mean field model, including the σ, ω, ρ and δ mesons, with density dependent couplings, as well as the electromagnetic interaction . Numerical results are presented for the asymmetry, charge and weak charge radius.
