Three-body photodisintegration of $sup 3$He
Cross sections for three-body photodisintegration of $sup 3$He 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 s-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 $sup 3$He($gamma$,n)2p total cross section has a peak value of approximately 1 mb. (2) The neutron spectra for $sup 3$He($gamma$,n)2p and the proton spectra for $sup 3$He($gamma$,p) np peak sharply in the region of the strong p-p final state interaction. (AIP)
