Using a high-resolution electron-impact energy-loss spectrometer we have measured the energy-loss spectra of electrons scattered near the forward direction from HgCl/sub 2/ and HgBr/sub 2/, for incident energies of 200 eV and energy-loss between 4 and 14 eV. Under these conditions the energy-loss spectra correspond closely to optical-absorption spectra. In addition to the well known /sup 1/Pi/sub u/ and /sup 1/summation/sup +//sub u/ absorption bands, we observe many new energy-loss processes beginning at 7.9 eV in HgBr/sub 2/ and 8.60 eV in HgCl/sub 2/. The relative cross sections and energies of these processes are in excellent agreement with those inferred as being necessary to account for discharge and fluorescence measurements in e-beam sustained mercuric bromide lasers.
