Abstract：
The projectile-like fragments emittd from 46.7MeV/u ¹²C induced reactions have been measured.The most probable energies of the PLFs due to the projectile fragmentation can be reproduced within the Abrasion picture.Their parallel momentum distribution widths are found to fulfill the Goldhaber relation and the extraced reduced parallel momentum distribution width σ₀ is 80±10MeV/c,which is close to the value obtained in the relativistic energy region.Futhermore,the values of σ₀ are the same for different reaction systems in our experiment.
