Investigation of the production of slow particles in 60 a (GeVO)-O-16 induced nuclear emulsion reaction

The multiplicity distributions and correlations of grey track producing par ticles (N-g), black track producing particles (N-b) and heavy track produci ng particles (N-h) have been studied in 60 A (GeVO)-O-16 induced nuclear em ulsion reaction. The multiplicity distributions of grey particles,black par ticles and heavy track producing particles can be reproduced by FRITIOF (ve rsion 1.7) taking cascade mechanism into account and DTUNUC 2.0 with an inc ident energy of 200 A GeV. The mean multiplicity of black particles <N-b> i ncreases with the number of grey particle N-g up to 10 and then exhibits a saturation for peripheral,central and mini-bias events;the average values o f grey particles <N-g> (heavy track producing particles <N-h>) increase wit h increasing values of black particle N-b (grey particle N-g).
