Projectile Fragmentation Reactions Induced By 46.7 Mev/U C-12

The projectile-like fragments (PLF) emitted at forward angles in 46.7 MeV/u C-12 induced reactions on different target nuclei have been measured. It was found the most probable energies of PLF products can be interpreted in the framework of an Abrasion model. The longitudinal momentum distribution widths fulfill the Goldhaber formula, and the reduced longitudinal momentum distribution width, extracted from the experiment sigma0 is 80 +/- 10 MeV/c, which is close to the value obtained in relativistic energy region. After averaging over many fragments, the sigma0 is nearly the same for different systems studied.
