Abstract
The C-12(gamma,p) differential cross-section in the Delta-resonance re gion has been measured using tagged photons, Data are presented for 20 MeV wide photon energy bins at 200, 300, 400 and 500 MeV and for prot on angles from 52 degrees to 128 degrees. The present C-12(gamma,p) me asurements are compared with previous experiments carried out at Frasc ati, Tokyo and Bonn. Comparisons are also made with theoretical calcul ations developed at Gent and Valencia which provide an interpretation of the photon reaction mechanism in terms of the major contributing pr ocesses. Coincidence data with correlated neutrons, protons and pions are also presented.
