  A relativistic model for quasielastic (QE) lepton-nucleus scattering is
presented. The effects of final-state interactions (FSI) between the ejected
nucleon and the residual nucleus are described in the relativistic Green's
function (RGF) model where FSI are consistently described with exclusive
scattering using a complex optical potential. The results of the model are
compared with experimental results of electron and neutrino scattering.
