Abstract

The electronuclear measurements always include the background from the (e+, e–)-pair photoproduction reaction in the target. The attempt to take into account this background through its computation by usual methods with applying the computation program GEANT-3 has appeared impractical, since it would take several years for the PC to operate. The present paper describes the technique, which permits one to reduce the time required for the PC computation of the background to a few hours. The developed technique has been verified by carrying out computations of the background from the (e+, e–)-pairs for the conditions, at which this background was measured at Saclay. The comparison between the calculated data and the experimental results has shown their agreement.
