scattered electrons from Hg atoms have been computed for scattering angles 0–180 in the
energy range 1 eV $\leqslant\,{E} _ {i}\leqslant 2\,\mathrm {keV} $. An optical model
approach is employed using a complex optical potential within the framework of the Dirac
relativistic partial wave analysis. We compare our results with recent experiments and
available theoretical calculations and find a reasonable agreement with experiments over a …
