[en] Two-particle correlations have been measured at GANIL with a multidetector array of 21 telescopes (a part of which was set-up in a close-packed geometry). Simultaneously a plastic wall, made of 96 scintillators, set-up at foward angles, was triggered either by coincidence events or single events. The correlation functions R, are measured for different sets of light particles. They are also studied versus collective data given by the plastic wall detection of each event. We deduce different informations concerning the spatial extent of the emitting source, as well as the population of particle unstable states of light nuclei
