Abstract
Cross sections for three-body photodisintegration of are calculated in the electric dipole approximation. The calculation is performed within the context of exact three-body theory with the two-nucleon interactions represented by -wave spin-dependent separable potentials fitted to low-energy nucleon-nucleon scattering data. The photodisintegration amplitude is expressed in terms of the fully off-shell nucleon-plus-correlated-pair amplitudes, a method applicable to any weak-process disintegration amplitude. The numerical results indicate: (1) The total cross section has a peak value of approximately 1 mb. (2) The neutron spectra for and the proton spectra for peak sharply in the region of the strong final-state interaction.
