Abstract
The two-body photodisintegration of into a proton and a triton has been studied using the CEBAF Large-Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Accelerator Facility. Real photons produced with the Hall-B bremsstrahlung-tagging system in the energy range from to GeV were incident on a liquid target. This is the first measurement of the photodisintegration of above GeV. The differential cross sections for the reaction were measured as a function of photon-beam energy and proton-scattering angle and are compared with the latest model calculations by J.-M. Laget. At GeV, our data are in good agreement only with the calculations that include three-body mechanisms, thus confirming their importance. These results reinforce the conclusion of our previous study of the three-body breakup of that demonstrated the great importance of three-body mechanisms in the energy region GeV.
