The momentum spectra of particles emerging at 30° to a 30-GeV proton beam impinging upon various targets were measured using time-of-flight techniques. Intensities of protons, antiprotons, $\pi$ mesons, $K$ mesons, deuterons, and tritons in the range 1 to 3 GeV/c are given. Particular attention is given to the tritons and deuterons emitted from the different targets. Possible mechanisms for their production are discussed.
