Abstract
It is shown that the Fisher droplet model, percolation, and nuclear multifr agmentation share the common features of reducibility (stochasticity in mul tiplicity distributions) and thermal scaling tone-fragment production proba bilities are Boltzmann factors). Barriers obtained, for cluster production on percolation lattices, from the Boltzmann factors show a power-law depend ence on cluster size with an exponent of 0.42 +/- 0.02. The EOS Collaborati on Au multifragmentation data yield barriers with a power-law exponent of 0 .68 +/-. 0.03. Values of the surface energy coefficient of a low density nu clear system are also extracted.
