Cross-section excitation-energy spectra and angular distributions were measured for the {sup 2}H({ital p},{ital n})2{ital p} reaction at 135 MeV in 6{degree} steps from 0{degree} to 30{degree} (laboratory), using the beam swinger facility at the Indiana University Cyclotron Facility. The target was a 12.8 mg/cm{sup 2} foil of CD{sub 2}. 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{degree} spectrum is dominated by a large peak near 0 MeV of relative energy in the final 2{ital p} system; this peak corresponds to the two protons in the {sup 1}{ital S}{sub 0} 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. {copyright} {ital 1996 The American Physical Society.}
