γnPartial Cross Sections up to 12 GeV and the Isovector-Isoscalar Interference

Abstract
γn reactions are studied in a 40-in. bubble chamber filled with deuterium. Cross sections for channels with no neutral particles in the final state are presented up to a photon energy of 12 GeV. For channels with one neutral particle we present the cross sections at 7.5 GeV only. Comparison of γn reactions with their charge-symmetric γp reactions indicates a considerable isovector-isoscalar interference contribution.
