Abstract

Isotopically resolved yields of complex particles and fragments from the reaction C12 on Au197 at three bombarding energies EA=30,48, and 84 MeV were measured. Specific entropies SA were derived from the isotope yield ratios using a quantum statistical model. The entropy increases with the bombarding energy in the case of preequilibrium light particles but, for intermediate mass fragments, has an energy-independent value of SA2.3.
