Differential cross-section measurements ofK+n→K0patK+momenta of 0.7, 0.8, and 0.9 GeV/c

Abstract

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.
