Multiplicity and angular distributions of shower, grey, and black particles produced in the interactions of S32 at 200A GeV, O16 at 200 and 60A GeV, and He4 at ∼140A GeV in emulsion are compared with the predictions of a Monte Carlo code which takes into account the internuclear cascading. The correlations between the various parameters belonging to the same or to the different kinds of particles are discussed. The data on shower and grey particles from all the beams are well described by the code. However, the black prong data show a significant departure from this model.

We report the multiplicity and angular distributions of the low energy target-associated particles from 32S and 16O induced reactions at 200 GeV/nucleon and 16O induced reactions at 60 GeV/nucleon in emulsion. The results are compared with the Monte-Carlo Code VENUS.

THE FORWARD AND BACKWARD HEMISPHERE ARE DEFINED AS MULT(Q=FORWARD) WHEN COS(THETA) > 0 AND MULT(Q=BACKWARD) WHEN COS(THETA) < 0.
Partial production cross sections of projectile alpha fragments produced in high-energy interactions of 16 O and 32 S at 200 GeV/n and 16 O at 60 GeV/n in emulsion are studied. Evidence of multiplicity scaling of such produced fragments is presented in the energy range 2–200 GeV/n for various projectiles.

Pseudorapidity distributions of relativistic singly charged particles in oxygen-induced emulsion interactions at 14.6, 60, and 200 GeV/nucleon are studied. Limiting fragmentation behavior is observed in both the target and projectile fragmentation regions for a central as well as for a minimum-bias sample. Comparisons with the fritiof model reveal that the picture of fragmenting strings successfully describes the observed data.
