摘    要:We present the experimental isotopic distributions of the ^18N projectile fragmentation products Li,Be,B and C in coincidence with neutrons,as well as the inclusive ones on ^197Au and ^9Be targets.In the framework of the abrasion-ablation model,these distributions are calculated for various nucleon density distributions of the projectile.The comparison with experimental isotopic distributions of the projectile-like fragments in coincidence with neutrons shows that the information on the nucleon density distribution of the ^18N projectile can be extracted.
