Abstract
Cross sections for electron-mercury scattering at incident electron energies from 0.1 to 1.4 eV have been calculated by numerical solution of the Dirac equation including exchange and a polarization potential but not coupling to inelastic channels. A resonance has been found in the p1/2 partial wave at about 0.2 eV which appears to correspond to the (6s26p1/2)2P1/2 ground state of Hg. This is probably the resonance observed experimentally by Burrow and Michejda (1975) at 0.63 eV.
