Abstract

The three-body reaction C13(p,pn)C12 has been studied experimentally in a kinematically complete experiment. pn coincidence events were measured for several bombarding energies between 7.9 and 12.5 MeV using associated time-of-flight techniques, pulse-shape discrimination for the neutron-detection system, and a silicon surface-barrier detector for the charged particles. Only in the region of 12.5-MeV bombarding energy is there an indication of sequential decay via "singlet deuteron" formation. Higher energies were not attainable with the available equipment, and at lower energies sequential decay through levels in C13 and N13 was relatively strong and obstructed the observation of possible contributions from pn final-state interactions. An upper limit is assigned to the two-body (p,d*) cross section.
