Statistical model analysis of ALADIN multifragmentation data

Abstract

Using a statistical model for nuclear multifragmentation we analyze the ALADIN multifragmentation data from Au induced reactions on various targets at a beam energy of 600 MeV/nucleon. By adjusting excitation energies of fragmenting heavy residues such that the correlation between the average multiplicity of intermediate mass fragments versus Zbound can be well reproduced, we find that all experimental observables which we have studied can be well reproduced simultaneously. The extracted excitation energies of heavy residues provide a strong constraint on the reaction dynamics leading to the formation of the residues. © 1993.
