Abstract

Problem statement: The interactions of 24Mg at 4.5A GeV/c with an emulsion can reveal some compound multiplicity characteristics. Approach: Furthermore, the number of grey and shower particles taken together a termed the compound multiplicity. Results: The results revealed that the compound multiplicity distributions become wider with increasing the size of the struck nucleus and the value of the c> increases with increasing mass of the projectile and target. Moreover, the average compound multiplicity is found to vary linearly with shower, grey, black and heavily ionized particles. On the other hand, the mean multiplicities of shower, grey, black and heavily ionized particles increase with an increase in the number of compound multiplicity. Meanwhile, the dependence of shower, grey and black particles emitted in the forward and backward hemispheres on the number of compound particles emitted in the forward and backward hemispheres is also investigated. Conclusion: Finally, the ns distributions obey the KNO scaling (i.e., the multiplicity distribution has a universal behavior when it is rescaled to the  s>.
