Multifragmentation has been studied for {sup 36}Ar-induced reactions on a {sup 197}Au target at E/A = 80 and 110 MeV and for {sup 129}Xe-induced reactions on several targets ({sup nat}Cu, {sup 89}y, {sup 165}ho, {sup 197}Au) and E/A = 40, 50 and 60 MeV. The probability of emitting n intermediate-mass-fragments is shown to be binomial at each transversal energy and reducible to an elementary binary probability p. For each target and at each bombarding energy, this probability p shows a thermal nature by giving linear Arrhenius plots. For the {sup 129}Xe-induced reactions, a nearly universal linear Arrhenius plot is observed at each bombarding energy, indicating a large degree of target independence.
