Study of the 12C+197Au reaction at relativistic energies with the INDRA 4pi multidetector

Abstract : The INDRA@GSI experiment permits to explore the mechanisms of the reaction 12C+197Au in normal kinematics by the use of the INDRA 4p multidetector and relativistic 12C beams. The target spectattor source is determined for protons and light fragments, separately from the early cascade source emitting light particles and a high energy source producing fragments approximately in the center of mass. The proton kinetic energy soectra are compared to combinations of the Liège IntraNuclear Cascade model and statistical models. The favoured scenario associates a cascade process with a statistical multifragmentation process. The fragmenta slope temperatures determined by a Maxweel-Boltzmann function combination emphasize a dependence on incident energey, with the reaction centrality given by the charged particle multiplicity. The pions, for the first time detected in INDRA, and the fast protons emitted in the early stage of the reaction present a correlation with the impact parameter but not with the fragment production.
