|Abstract:||Multiplicity correlations of low-energy pions and energetic protons with intermediate-mass fragments were measured for 12C + 197Au collisions at incident energies from 300 to 1800 MeV per nucleon with the 4P INDRA multidetector. The deduced correlation functions 1 + R ~ 1.3 for inclusive event samples reflect the common impact-parameter dependence of the considered multiplicities. For finite bins in charged-particle multiplicity, the correlation functions are close to unity and exhibit a multiplicity dependence that does not indicate strong direct correlations. Only for pions at high particle multiplicities (central collisions) a weak anticorrelation is observed. Overall, the results are consistent with the equilibrium assumption made in statistical multifragmentation scenarios. Predictions obtained with intranuclear cascade models coupled to the Statistical Multifragmentation Model are in good agreement with the experimental data.|
