Is the breakup time a free parameter when describing heavy ion collisions?

Abstract

Thermodinamic descriptions of heavy ion collisions generally include the so called breakup time (when to switch from continuum picture to a collisionless gas). While an appropriate choice of this time can help to reproduce the detected spectra, from the same reason this freedom may prevent us to reconstruct uniquely the compressed hot stages from the observables. This problem is absent if the calculated final spectra are insensitive on the breakup time at least in a domain. Here we show such an example in a model system. This example may give further arguments for the thermodynamic description. (author) 13 refs.; 4 figs.
