Résumé : The main points of a new experiment being prepared currently at GANIL are reported. Simultaneous measurement of two-nucleon (nn, pp, np) correlations at small relative velocities will be performed. Special attention is paid to (nn) correlations as free of Coulomb effects. The physical goal of experiment is to find the space-time properties of nucleon emission dynamics in heavy-ion collisions and to clarify some related questions: sequence of particle emission, three-body Coulomb effects, deuteron production mechanism etc.
