The cross section for the reaction 7 + C -+e+ + e+ C has been measured for a series of kinematic points giving nuclear momentum transfers in the region 0.2 0.7 F -2 , with incident -photon energies in the region for photoproduction of the first two pi-nucleon resonances. Measurements were made, using asymmetric detection geome-try, of e3.ectron and positron cross sections for each point. The ch...
