The production of K ∗±(892) and K S 0 are studied in pp annihilations at 0.76 GeV/ c. Longitudinal and transverse momentum distributions are presented. The ratio σ( K ∗+) σ dir ( K 0 ) is found to be 0.09 ± 0.09, where σ dir(K 0) refers to kaons which do not arise from decay of the resonances. The ratio of strange to non-strange directly produced vector mesons is K dir ∗+ ϱ dir 0 = 0.054 ± 0.005 , compared to the corresponding ratio for the pseudoscalar mesons K dir 0 π dir − = 0.021 ± 0.003 . It is deduced that (50±5)% of all K S 0 are indirectly produced through the decay of the meson resonances and consequently (50±5)% are directly produced.
