The multiplicity correlations amongst the singly (NP) and doubly (Nalpha) charged projectile fragments and the secondary charged target fragments (black, grey and shower tracks) produced in 32S–Emulsion interactions at 3.7A and 200A GeV are studied to shed some light on the interface of spectator and participant region. The effect of changing the energy used for 32S-Emulsion interactions is investigated as well, indicating that the values of ˂ NP ˃ and ˂ Nalpha ˃ at both incident energies having the same values within experimental errors. With an increasing number of singly charged projectile fragments NP, the impact centrality is shown to be increased. The correlation between the mean multiplicities of secondary charged particles and both of the singly and doubly charged projectile fragments are observed. The relation between the variation of mean values of black and heavy ionized particles is observed and found to be independent of the production of singly charged fragments
