The WA94 experiment uses the production of strange particles and antip
articles to investigate the properties of hot hadronic matter created
in heavy-ion interactions. Lambda, <(Lambda)over bar>, Xi(-) and <(Xi)
over bar>(+) particle yields and transverse mass spectra are presented
for pS interactions. These results are compared with those from SS in
teractions. Our results are also compared with those from pW and SW in
teractions of the WA85 experiment. (C) 1997 Published by Elsevier Scie
