We compile 181 papers report p̄p, p̄n, p̄d, n̄p, n̄n, and n̄d reactions in flight for beam momenta up to 50 GeV/c. We display, as a function of incident momentum, total and channel cross sections, elastic and two-body inelastic differential cross sections, and polarization in elastic scattering, as well as our fits to the elastic differential cross sections. We also provide indices to the papers, as well as a complete listing of the selected data. The approximate cutoff date for the literature search for this report was September 1, 1971.
