“…This suggests that cluster size does not depend on the nature and energy of the primary particle. Furthermore, comparing these results with those obtained by other workers (20,24) in h-h and h-A interactions with Nh 2 2 at different incident energies, one may conclude that the mechanisms of multiparticle production in the total breakup of the target nucleus and in hadronic reactions are probably similar.…”

“…Several investigators (15)(16)(17)(18)(19)(20)(21)(22)(23)(24) have observed that the study of the dynamics of cluster formation and their sizes in highenergy hadronic interactions might reveal useful clues in the understanding of the mechanism of multiparticle production. Many workers are of the opinion that the particles produced in the intermediate stage show a tendency to form clusters; these clusters thereafter decay into charged shower particles.…”

Analysis of the events having Nh 2 28 produced in 50 GeV pion (T)--Em and 400 GeV proton (p)-Em interactions and the results obtained at different incident energies reveal that the probability of total disintegration of the target nuclei and the value of (N,) strongly depend on the mass of the incident particle as well as the target nuclei. This probability is observed to be independent of the energy of the projectile in p-Em reactions but not in ern collisions. The mean normalized multiplicity, R4, calculated in terms of the created charged particles, is independent of the identity and energy of the impinging hadron beyond -20 Gev. Furthermore, the values of ( T ) and D(T) are observed to depend weakly on the energy of the projectile. The maximum number of charged particles constituting a cluster is observed to be four at both incident energies; the characteristics of clusters are observed to be independent of the nature and energy of the impinging hadron.L'analyse des Cvenements avec Nh 2 28 produits dans les interactions de T-de 50 GeV ou de p de 400 MeV avec des noyaux lourds dans les Cmulsions, ainsi que les rCsultats obtenus a differentes tnergies incidentes, rCv2lent que la probabilitt d'une dCsintCgration totale des noyaux cibles et la valeur de (N,) dependent de la masse de la particule incidente aussi bien que des noyaux cibles, alors qu'on observe que cette probabilitC est indtpendante de 1'Cnergie du projectile dans le cas des reactions p mais non pas dans le cas des collisions T-. La multiplicitC normalisCe moyenne, R4, calculCe en termes des particules chargees qui sont crCCes, est independante de l'identite et de l'energie du hadron incident au-dell d'environ 20 GeV. On observe de plus que les valeurs de ( v ) et D ( q ) dependent faiblement de 1'Cnergie du projectile. On observe aussi que le nombre maximum de particules chargtes constituant un amas est quatre pour les deux Cnergies incidentes, et que les caractkristiques des amas sont indkpendantes de la nature et de 1'Cnergie du hadron incident.[Traduit par le journal]Can.
