Description
Thick-target recoil properties of seven fragments ranging from 24Na to 52Mn produced in the interaction of 18.5 GeV 12C 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. While the properties associated with the ablation step (range and kinetic energy) obey the hypothesis, those associated with abrasion (F/B, β/sub vertical-barvertical-bar/) do not, there being a approx.30% enhancement in these values in reaction induced by 12C ions. The scaling power of various energy related variables is examined and the systematics of the recoil parameters are developed. The implications of these results for the reaction mechanism are considered
