K/subL/0p charge-exchange scattering from 550 to 1000 MeV/c

Employing a neutral kaon beam at the Argonne Zero Gradient Synchrotron, a high-resolution magnetic spectrometer, and a neutron detector, differential cross sections have been obtained in the forward direction [0.045 < vertical-bar t vertical-bar < 0.18 (GeV/c)2] for the reaction K0/subL/p → K+n. Previous studies of the time-reversed process in deuterium, K+d → K0p (p), have not yielded direct cross-section measurements in the forward direction because there is an inhibition of the non-spin-flip process in deuterium due to the Pauli exclusion principle. Nevertheless, our data are in agreement with the extracted free-neutron cross sections of deuterium studies as determined from the impulse and closure approximations
