Abstract

The degree of excitation of the emulsion target nuclei due to nuclear interactions of oxygen and sulfur projectiles at 200 GeV/nucleon incident energy has been investigated. Using the plausible assumption that the number Nb of slow particles emitted from the struck target nucleus can be interpreted as a measure of the temperature T of the residual nucleus, we have found that there exists a critical temperature Tc of the excited target nucleus. For Ag and Br target nuclei this temperature corresponds to {all equal to}12 and it is attained when the impact parameters are less than about 4 fm. © 1993 Springer-Verlag.
