Statistical and microscopic description of energetic products in the reactions induced byO16onAl27,Ni58, andAu197at 94 MeV/nucleon

Protons and charged pions have been detected at 70°, 90°, and 120° in the reaction induced by ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ on various targets at 94 MeV/nucleon incident energy. Measured energy spectra are analyzed in terms of statistical emission from equilibrated sources in a participant-spectator picture. Microscopic dynamical calculations based on the Boltzmann-Nordheim-Vlasov equation are also performed. Experimental data are well reproduced by both models.
