Cross-section excitation-energy spectra and angular distributions were measured for the 2H(p,n)2p reaction at 135 MeV in 6° steps from 0° to 30° (laboratory), using the beam swinger facility at the Indiana University Cyclotron Facility. The target was a 12.8 mg/cm2 foil of CD2. Neutron energies were measured by the time-of-flight method using large-volume plastic scintillator arrays at flight paths of 91 m. The overall energy resolution was 260 keV. The 0° spectrum is dominated by a large peak near 0 MeV of relative energy in the final 2p system; this peak corresponds to the two protons in the 1S0 state. The wider-angle spectra are dominated by a broad peak centered at 10 to 20 MeV of excitation which is the quasifree scattering peak. The spectra are compared with impulse approximation and three-body Faddeev calculations.
