The maximum breakup of 16O + 107Ag and 84Kr + 107Ag collisions at energies from 5Ato 2100AMeV has been investigated. Comparisons between data and calculations within a fusion + evaporation model at low energies and fusion + hadrochemical fireball decay model at higher energies show that phenomena like pre-equilibrium emission, compression and collective flow must be considered. At (34 ± 2)AMeV we observe the cease of the compound evaporation process and the onset of multifragmentation for the highest multiplicity 16O + 107Ag collisions.
