Abstract

The 2H(p, pn) reaction has been studied at a bombarding energy of 9.0 MeV and several coincidence detection angles using the Rice University tandem Van de Graaff accelerator and computer-analyzer system. The energies of the detected, coincident particles were determined using a solid-state surface barrier detector for the proton and time-of-flight measurement on the neutron. The contributions of the neutron-proton final state interaction and neutron-proton quasi-free scattering have been observed. The final state interaction contribution has been reproduced using Phillips, Griffy and Biedenharn theory. The shape of quasi-free scattering contribution spectrum is in reasonable agreement with simple impulse approximation prediction. The absolute value of cross section is smaller than predicted by spectator model calculations.
