ResumoIn an experiment with the CERN 2m deuterium bubble chamber the reaction K+d→Kopp (1) and the related reaction K+n→Kop (2) are studied at an incident momentum of 4.6 GeV/c. The cross section for the latter reaction is found to be slightly larger than the cross section for the reaction K−p→Kon at the same energy. The corresponding differential cross sections agree within the rather large uncertainties. The forward amplitude for reaction (2) is predominantly real. Moreover, the total and forward differential charge exchange cross section values are compatible with those predicted on the basis of an SU (3) sum rule. A comparison of the K±-charge exchange differential cross sections with the predictions of a Regge pole model is also presented.
