Abstract:

Fe-, Kr- and Xe-induced heavy-ion reactions at show factorization in the production cross-sections only for light fragments. Both "strong'' and "weak'' factorization are found for light fragments. The cross-sections of these fragments are described in detail within the prescription of cold breakup of spectator residues.
