Abstract
The longitudinal-momentum distributions of projectile fragments from 0 .8 A GeV Xe-136 and 1 A GeV Au-197 projectiles impinging on targets of beryllium and aluminium, respectively, have been measured using the p rojectile-fragment separator FRS at GSI. Different momentum distributi ons have been found for two different classes of fragmentation process es: the abundant hot fragmentation with several nucleons evaporated fr om the prefragments, and the rare cold fragmentation with only protons removed from the projectile, but no nucleons evaporated. The data are compared to model calculations.
