RESULTS FROM THE NA36 EXPERIMENT ON THE PRODUCTION OF STRANGENESS VERTICAL-BAR-S-VERTICAL-BAR=1 AND VERTICAL-BAR-S-VERTICAL-BAR=2 PARTICLES

Measurements of the production of singly and doubly strange particles in S + Pb collisions at a beam momentum of 200 GeV/c per nucleon are p resented. The yield of singly strange particles as a function of negat ive particle multiplicity has been measured. Rapidity and transverse m omentum distributions from events consistent with a maximum impact par ameter of 9 fm are compared with the predictions of Fritiof 7.02, Venu s 4.10 and RQMD 1.08. The comparison illustrates the importance of re- interactions of secondaries and suggests that additional physical proc esses are required to be incorporated into the event generators. The a nalysis of strange particle ratios indicates that strangeness phase sp ace is not saturated in these collisions.
