In this work we present some general characteristics of inelastic interactions of 3 A GeV/c 7 Li projectiles with emulsion nuclei. The mean free path is measured and found to agree with the different theoretical parameterizations. The multiplicity characteristics for interactions were studied and separated into (H),(CNO) and (AgBr) groups. The KNO type of scaling behavior of the multiplicity distribution is well satisfied by all target protons produced due to 7 Li-Em and 7 Li-AgBr interactions at 3 A GeV/c. Azimuthal correlations in angles between various types of charged secondary particles have been investigated.
