  In the first Born approximation and using an elliptically polarized laser
field, the Mott scattering of an electron by a Coulomb potential is
investigated using the Dirac-Volkov states to describe the incident and
scattered electrons. The results obtained are compared with the results of S.M.
Li \textit{et al} \cite{1} for the case of a linearly polarized laser field and
with the results of Y. Attaourti \textit{et al} \cite{2} for the case of a
circular polarization.
