[en] The results on p-p and p-d correlation functions measured in recent experiments at GANIL are presented. The contribution of both preequilibrium and equilibrium protons is observed for the first time in the same experiment (ORION) and a strong dependence of the correlation function on impact parameter selection and directional cuts is seen. A shorter emission time of deuterons compared to that of protons is observed using the new method based on the directional dependence of the correlation function of non identical particles. The two-proton correlation function is measured in previously unaccessible region of very small relative momenta 1-10 MeV/c especially suited to extract with high accuracy the lifetime value of an equilibrated long-lived source. The Coulomb directional effect in p-p correlations is observed for the first time, giving the additional information on lifetime and kinematic characteristics of the emitter.
