Isotopically resolved yields of complex particles and fragments from the reaction /sup 12/C on /sup 197/Au at three bombarding energies E/A = 30, 48, and 84 MeV were measured. Specific entropies S/A 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 S/Aapprox. =2.3.
