Abstract

The decay of nuclei excited via the annihilation of 1.2 GeV antiprotons has been investigated. Thanks to the ability to determine the excitation energy, E*, for all events, largely irrespective of their mass partitions, the probabilities of the different channels at play could be estimated as a function of E*. The data show the prevalence of fission and evaporation up to E*= 4 MeV/nucleon, with no hint of a transition towards multifragmentation.
