Longitudinal-momentum spectra are presented for the production of K /sup +/ and pi /sup +/ mesons at the CERN ISR at a transverse momentum of 0.8 GeV/c and a total c.m. energy of 44.6 GeV. Proton spectra for transverse momenta between 0.7 and 1.2 GeV/c are also given. The spectra cover a range of 0.2 to 1.0 in the Feynman variable x=2p/sub L // square root s. The pi /sup +/ spectrum agrees well with scaling when compared with accelerator data, while the K/sup +/ spectrum is consistently above the scaling prediction. The proton spectra have pronounced peaks at x=1, minima near x=0.9 and broad maxima at x=0.6. The data are compared with triple-Regge and diffraction dissociation models. (9 refs)
