Fragments in heavy ion collisions in a hydrodynamic approach with a nonequilibrium equation of state

Abstract

A hydrodynamic approach with a nonequilibrium equation of state is used to describe heavy ion collisions at medium energies. This approach includes describing the compression, dilution, and freeze-out stages of a hot spot formed during a heavy ion collision. The calculated energy spectra of protons and light ⁴He, ⁷Li, ⁹Be fragments produced in the ¹⁴N + ¹²⁴Sn reaction at a ¹⁴N ion energy of 32 MeV/nucleon are compared to experimental data.
