Results on the measurement of inclusive K-S degrees, n and <(Lambda)ov
er bar> production cross sections and rapidity distributions for antip
roton interactions on lead, copper and carbon nuclear targets at beam
momenta of 5.2, 7.0 and 8.8 GeV/c are reported. Simulations employing
a conventional Intra-nuclear cascade model were able to reproduce the
experimental results. Hence, no compelling evidence for the formation
of exotic quark-gluon states of matter was found.
