This kinematically complete experiment measured the three-body photodisintegration of /sup 3/He in the photon energy range of 35 to 65 MeV by means of the coincident detection of a proton and a neutron. The bremsstrahlung beam used was produced by a 68.4 MeV, 0.75 ..mu..A beam of electrons from the 100% duty cycle accelerator Microtron Using a Superconducting Linac (MUSL II) at the Nuclear Physics Laboratory of the University of Illinois at Urbana-Champaign. The /sup 3/He target gas was maintained at 4.3 K and 514 Torr. The proton telescope, neutron detector and associated electrons were calibrated by the use of deuterium. The quasideuteron effect could be distinguished in the data at around 45 MeV and predominates by 60 MeV. The strength of the effect was around 50 to 60 ..mu..b/sr/sup 2/. However, this cross section was separated by a primitive procedure; the interference between this and the competing final state interactions was not taken into account. By integrating over the neutron angles, a single differential cross section was generated and found to be about 0.6 times the deuterium cross section from 50 to 65 MeV. The neutron-proton final state interaction was clearly seen in the data. It is hoped this experiment will be an inducement for a complete theoretical treatment applicable to these energies.
