Fragment mass distribution from 1 GeV protons on ²⁰⁸Pb computed with PEANUT (dark cyan symbols) and compared with experimental data (red symbols [34]). Experimental data were actually measured at GSI in reverse kinematics. Also shown in the figure is the fragment mass distribution after the cascade stage (green symbols), and after the pre-equilibrium stage (dark blue symbols). The coloured blobs and the associated labels show the various processes resulting in the different ranges of product masses.
