Recent interest in the low-energy kaon-nucleon system has been substantially motivated by the possible existence of an exotic positive-strangeness, isospin-zero baryon resonance. We report here measurements of the cross section and differential cross section for K+n charge-exchange scattering in our exposure of the BNL 30-inch deuterium bubble chamber to a K+ beam at 0.7, 0.8; and 0.9 GeV/c. We compare our results with previous results and with the predictions of a recently published phase-shift analysis.

We present results on the differential cross sections for the process K + n → K 0 p extracted from the reaction K + d → K 0 pp measured at 13 momenta between 0.64 and 1.51 GeV/ c .
