• The spectrta of electrons enaitted in the forward direction from antiproton and pro-ton bombardments on carbon foils have been studied for projcctile energies from 500to 750 keV. Our main observ;ttion is that at the electron energy where the well-knownconvoy peak is observed for proton impact, the spc:ctrum for c>quivelocity antiprotonsis smooth, showing no indication of a deep anticttsp. However, around 50 eV belowthe electron energy where the cusp is observed for proton impact, we have observed asmall peak for antiproton impact. The energy and the relative intensity of the bumpare found to be consistent with those predicted for electrons released from a wakeriding state.
