Abstract
A binomial reducibility and thermal scaling analysis is performed on well-chacracterized thermal-like sources formed in reactions. The fragment probability distributions are shown to be binomial when plotted as a function of the measured excitation energy and the binomial elementary probability p is shown to follow the expected Boltzmann factor: Binomial reducibility and thermal scaling are explored also using global variables other than and the effect of source size on the binomial parameter p and m is shown. Finally, the extracted probability p is found to be correlated with the experimentally deduced fragment emission time up to about of excitation energy, hinting at a possible transition in decay mechanism above that excitation energy.
