Charge partition probabilities in the 32S + 27Al reaction at 37.5 MeV/nucleon analysed using the Boltzmann distribution

Abstract

We apply the Boltzmann distribution to charge partition probabilities measured with the AMPHORA multidetector in the reaction 32S + 27Al at 37.5 MeV/ nucleon. Approximate corrections to the data for pre-equilibrium emission are made and modifications to the basic formalism due to detection e?ciency and evaporation are treated explicitly. The data are well reproduced with a temperature of 5.0 MeV and a freeze-out volume which corresponds to densities which are 20 times smaller than normal density.
