Abstract The primary yield distribution of projectile-like fragments from the20Ne+197Au reaction has been reconstructed and was found to be similar when the bombarding energy is increased from 150 to 290 MeV. Alternative to theQ gg-systematics where the relative yields are ruled by exit channel properties, the Friedman model for projectile-fragmentation is successfully applied to the data. It relates the fragment yields essentially to the separation energyQ F of the clusters removed from the projectile (and transferred to the target) i.e. to entrance channel properties and was successful in describing the relative yields at very high bombarding energy (2 GeV/N). For a good reproduction of the relative yields at the bombarding energy and the heavy target of this experiment it is necessary to make a correction for neutron pick-up which accompanies the cluster stripping process with a certain probability. The predicted momentum widths of the fragment spectra, too, are consistent with the data.
