Cross sections for the formation of seven fragments ranging from /sup 24/Na to /sup 52/Mn in the interaction of 18.5 GeV /sup 12/C ions and 400 GeV protons with Cu, Ag, Gd, Ta, Au, and U have been measured. After correction for the difference in bombarding energy, the results were used to test the factorization hypothesis. Enhanced fragment emission in /sup 12/C reactions was observed for all targets excepting copper. The magnitude of the enhancement and its dependence on target and product A are described. The variation of fragment yields with target A is examined. The neutron excess products obey modified Qgg systematics while the neutron deficient ones do not. The implications of these results for the reaction mechanism are considered.
