摘要：
The emission of high-energy particles in the 16O + 197Au ion collision at an energy of 20 MeV/nucleon is considered in the context of hot spot time evolution with allowance for the hydrodynamic compression and expansion stages. In addition to our earlier consideration of this model, the evaporation of formed particles is included in spectrum calculation at the early (hot) stage of hot spot evolution. This leads to particle spectrum hardening in its high-energy part, in agreement with the experimental data. © 2011 Allerton Press, Inc.
