The results of an experiment to observe discrete energy gamma rays from anti pp annihilations at rest using a 750-MeV/c separated antiproton beam are described. The gamma spectra for all four energy leakage levels, summed over all charged particle multiplicities are shown for hydrogen and deuterium, respectively. It is concluded that to 1 percent of the continuum for discrete gamma lines between 50 and 200 MeV and with a 15 percent energy resolution one observes no structure in the gamma spectra of antiproton annihilations in hydrogen or deuterium.
