• We describe an applications-oriented method for determining continuum photonuclear angular distributions for emission of light particles (n, p, d, t, <SUP>3</SUP>He, and α) in the quasideuteron regime (40 ?? E<SUB>inc</SUB> ?? 140MeV). Based on theoretical considerations by Chadwick and Oblozinsky for the angular forward-peaking in preequilibrium reactions, Kalbachs 1988 angular distribution systematics for a neutron projectile can be straightforwardly modified for use in photon-induced reactions. This results in photonuclear angular distributions which are less forward-peaked than their nucleon-induced counterparts, due to the small momentum carried by a photon. Our predictions are compared against double-differential monochromatic <SUP>12</SUP>C (γ, xp) data at 60 and 80 MeV and are seen to describe the measurements fairly well.
