Abstract
Two mechanisms for the production of intermediate-mass fragments (IMF) were implemented in the statistical-model code ABLA07. At low excitation energies IMFs are emitted as evaporated nuclei. If the excitation energy of the system exceeds a given threshold, IMFs are formed in the simultaneous break-up of the system, modelled according to a power-law distribution, which is suggested by several theoretical models. The improved code was benchmarked on a large amount of experimental data, among which the high-precision data measured at GSI.
