Abstract

Problem statement: The process of nuclear fragmentation in interactions of 3.7A GeV 24Mg and 28Si nuclei with the different target nuclei in a nuclear emulsion have been investigated. Approach: The probability of interactions without any projectile fragment with charge Z≥2 is zero for hydrogen target, but increases by increasing the mass of the target. Results: The disruption of a projectile nucleus is more save in interactions with the heavy target nuclei than with the light ones. The nuclear fragmentation mechanism was investigated for shower and slow particles at Dubna energy. Several correlations between these particles are studied and analyzed. The variation of ng>/ns> with Nh behaves a straight line up to Nh = 14 in the collision of 24Mg and 28Si with emulsion nuclei, it reaches to constant value. These results are contradicted with that obtained from the light projectile nuclei such as p, d, 4He and 7Li with emulsion nuclei at the same energy. Conclusion: The behavior of the scale  shower (s>P (ns /s>) and compound (c>P (nc/c>) where (nc = ns+ng) particles are the same, also for both the collisions of 24Mg and 28Si with nuclei give the same behavior.
