Résumé : We present an analysis of the reaction K+p → K0 + anything at incident momenta of 5, 8.2 and 16 GeV/c in terms of the Björken variables gw and x. Assuming dominance of ρ{variant} exchange, we derive the structure function F2(x, y) which is found similar to the one obtained in deep inelastic electroproduction. © 1976.
