The yields and momentum distributions of heavy residues from the fragmentation of {sup 197}Au projectiles at 20MeV/nucleon by C, Al and Ti targets have been measured at 0 degrees. Projectile residues (and fission fragments) were analyzed using the A1200 mass separator at the NSCL and stopped in a Si-detector telescope placed at the focal plane of the separator. The nuclear charge, ionic charge, mass and momentum of the residues were deduced. The analysis of the data has shown that unit Z and A resolution is obtained for a broad range of reaction products, from near-projectile residues to fission fragments. The residue properties at this energy show a target dependence, in contrast to available data at higher energies. The momentum distributions indicate that incomplete and complete fusion (accompanied by fission or particle emission) and fragmentation are the main mechanisms contributing to the production of the residues at this energy regime.
