Résumé : The inclusive reactions K+p → K0 + X++ at 5.0 and 8.2 GeV/c and K+p → K0 + π+ + X+ at 8.2 GeV/c are analysed in terms of angular variables θ and ø. The data are compared and found consistent with various theoretical bounds on the s-dependence of the inclusive reaction cross sections. Experimental evidence is presented that dσ/dcos θ = a exp (-b sinθ) with b ∼ √s and a increasing with energy. Correlations between the angular variables and between the variable ø and the K0 and π+ momenta in the c.m.s. are observed and discussed. © 1972.
