Backward production of protons in nuclear reactions with 400 GeV protons

The measurement of invariant cross sections for the production of protons by 400 GeV protons from a variety of nuclear targets is described. Results are given for ⁶Li, Be, C, A1, Cu, and Ta at 70^∘{}, 90^∘{}, 118^∘{}, 137^∘{} and 160^∘{} for detected protons from 0.4 to 1.4 GeV/c. Some angular distributions are given over a wider selection of angles. Comparisons are made with observed experimental results at other energies.NUCLEAR REACTIONS Inclusive cross section, 400 GeV, ⁶Li, Be, C, A1, Cu, and Ta.
