Determination of Critical Exponents in Nuclear Systems
arXiv:nucl-ex/9607002
Abstract
Signatures of critical behaviour in nuclear fragmentation are often based on arguments from percolation theory. We demonstrate with general thermodynamic considerations and studies of the Ising model that the reliance on percolation as a reference model bears the risk of missing parts of the essential physics.
