An application of GEANT4 version 9.2p01 to 4π Medea detector will be presented. MEDEA (1) is a working array aimed at the gamma and light charged particle detection in the range of intermediate energies (up to 100 MeV/A), installed at LNS. MEDEA is made of 180 BaF2 detectors, arranged in a spherical shape of 22 cm radius. Each module is made of 2 separated crystals in optical contact. The interest in neutron detection to extend the knowledge of the reaction dynamics has triggered a study of a possible shortening of a few MEDEA modules with the aim of increasing path length for neutron detection, therefore improving their energy calculation through Time Of Flight determination. The MEDEA geometry has been implemented in the GEANT4 framework and the response of the whole system to sources of monochromatic neutrons up to 18 MeV, impinging on a module has been studied. Results and experienced problems will be shown. 1) E.Migneco, Nuclear Instruments and Methods, A314(1992)31


A study of the response of MEDEA array to neutron up to 20 MeV, based on GEANT4 will be presented. Results will be discussed.
