We address the problem of including Coulomb distortion effects in inclusive quasielastic (e,e )
reactions using the eikonal approximation. Our results indicate that Coulomb corrections may be-
come large for heavy nuclei for certain kinematical regions. The issues of our model are presented
in detail and the results are compared to calculations of the Ohio group, where Dirac wave functions
were used both for electrons and nucleons. Our results are in good agreement with those obtained by
exact calculations.
