摘要：

Multifragmentation for Xe-129-induced reactions on several targets (Cu-nat, Y-89, Ho-165, Au-197) has been studied at 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, p shows a thermal behavior as demonstrated by linear Arrhenius plots. A nearly universal linear Arrhenius plot is observed at each bombarding energy, independent of target. The sensitivity of p to the Z(threshold) points to its physical significance and rules out auto-correlation effects.
