Fragmentation in 28 Si-emulsion interactions at 3.7 A GeV

The results on fragmentation of a 3.7A GeV28Si projectile in interactions with different target nuclei in nuclear emulsion are presented. Limiting fragmentation behavior of the projectile fragments is achieved at this energy. It is shown that the factorization principle for fragmentation cross-sections holds for light fragments (Z ≤ 4) only. A bond percolation prescription is able to reproduce the experimental observations for fragments with charge 4 ≤Z ≤ 10. A rise in the production of helium fragments is also predicted by bond percolation.
