Transverse-momentum distributions of the residual charges due fragmentation of 16O projectile nucleus with emulsion at 3.7A GeV are investigated. The experimental parameters that study the mechanism responsible for projectile fragmentation are discussed. The angular distributions of all possible charges due to projectile fragmentations for 16O nucleus are recorded and compared that obtained for 12C, 22Ne, 24Mg and 28Si at the same collision momentum. The effects of target size on fragmentation process for both 16O and 24Mg projectiles are studied. The experimental results show that there is unified mechanism of projectile fragmentation in this range of masses and energy.
