Energy loss spectra of forward scattered He+ ions in collisions with HCl are reported for collision energies (E(lab)) in the range 20-60 eV. The spectra extend up to total energy transfers of about 2.5 eV, where the intensity is 6 orders of magnitude less than the elastic forward peak. At large ener...
