Résumé : Inclusive cross sections and one-particle inclusive spectra are given for neutral K, Λ and Λ produced in K-p and K+p interactions at 32 GeV/c in the 4.5 m Mirabelle hydrogen bubble chamber at the Serpukhov accelerator. Cross sections for associated production are also given, and the energy dependences of the cross sections and of the x distributions in the central and in the fragmentation regions are discussed. © 1975.
