Lambda-hyperon and K°-meson production effective cross sections in Interactions of relativistlc carbon nuclei, measured using a 2-meter propane bubble chamber, appear to be <^c « (24+6) mb; <7°°0- (30 ±10) mb. They are In fair agreement with the predictions of the flrestreak model making use of the hypothesis on chemical equilibrium and associative production of strange particles. It means that strange particle production In CC-lnteractlons at 4.2 GeV/c momentum per nucleon Is well described without Invoking hypothesis about the quark-gluon phase transition.
