  A completely antisymmetrized Green's function approach to the inclusive
quasielastic $(e,e')$ scattering, including a realistic one-body density, is
presented. The single particle Green's function is expanded in terms of the
eigenfunctions of the nonhermitian optical potential. This allows one to treat
final state interactions consistently in the inclusive and in the exclusive
reactions. Nuclear correlations are included in the one-body density. Numerical
results for the response functions of $^{16}$O and $^{40}$Ca are presented and
discussed.
