Study of forward–backward shower particle and slow proton production from the interactions of 7 Li with emulsion nuclei at 3 A GeV/c

The correlations between the multiplicities of secondary charged particles emitted in collisions of 3 A GeV/c⁷Li with emulsion have been studied. The dependence of the correlation strength on the mass number of the projectile has been analyzed. Moreover, the dependence of the average multiplicities of shower particle emitted in the forward and backward hemispheres on the number of target fragments has been investigated. The study of the number of backward slow protons (black and grey particles) indicates that, while the number of backward particles is a good factor representing the purely target fragments, the number of backward grey particles can be considered an accurate experimental factor for the impact parameter dependence of the collision
