Résumé : The inclusive reaction K+p → K0 + X is studied at 5, 8.2 and 16 GeV/c. The energy dependence and the shapes of inclusive spectra in the central region are found to be consistent with double-Regge expansion. With the values obtained for the parameters of the Regge expansion, prediction are made for the behaviour of the cross section at higher energies. © 1975.
