The number of hyperons (Λ) per participating nucleon is higher in A+A than in p+p collisions [1]. It is interesting to measure the detailed behavior of hyperon production as a function of the system size in order to determine the onset of this type of strangeness enhancement.
NA49 has taken data not only on Pb+Pb but also C+C collisions. The results from the light C+C system are compared to earlier measurements of Λ hyperons in central S+S (NA35), central Pb+Pb and p+p interactions.
