Abstract

The (gamma,NN) reactions at intermediate energies have long been suggested as a source of information on nucleon-nucleon correlations in nuclei. In particular, the (gamma,pp) reaction may hold particular promise because it is much less sensitive to medium range MEC effects. In the past limited intensity and resolution of the available photon beams has hindered progress. Using the Galsgow photon tagging spectrometers at the Mainz MAMI-A and MAMI-B electron microtrons, data on both (gamma,pn) and (gamma,pp) reactions in 12C have now been obtained with much improved energy resolution (~7 MeV in missing energy). The very recent MAMI-B data extends up to 750 MeV which permits shorter range effects to be sought
