Thermodynamical properties and deexcitation of sources involved in collisions between light nuclei around 100 AMeV incident energy

Abstract : Vaporization events, where all species have atomic numbers lower than 3, and deexcitation properties of quasi-projectiles involves in binary dissipative collisions between 36 Ar and 58 Ni are studied with the multidetector INDRA. Kinematical properties and chemical composition (mean values and variances) of vaporizing sources are derived over the excitation energy per nucleon range 8-28 MeV. These data are found in good agreement with the results of a model describing a gas of fermions and bosons in thermal and chemical equilibrium, which strongly suggests that thermodynamical equilibrium has been reached even for such sources produced in very extreme conditions of collisions. Finally, removing the constraint on atomic numbers lower than 3, the evolution of the chemical composition of quasi-projectiles is presented over the excitation energy range 0-25 AMeV.
