Nuclear emulsions are used to investigate spallations produced by 108 GeV/c 24Mg nuclei. The main experimental characteristics (inelastic cross-sections and multiplicities of various types of secondary particles and their dependence on the masses of the colliding nuclei) in inelastic interactions of 24Mg nuclei with nuclei of nuclear emulsion at 4.5 GeV/c per nucleon have been studied. The integral multiplicity distribution of disintegrated particles from target nuclei is used to separate the inelastic interactions with the free hydrogen (H), the light (CNO), and the heavy (AgBr) nuclei. Multiplicity scaling in the shower particles obeys a scaling function of Koba-Neilsen-Olesen (KNO) type in this energy region.
