Résumé : The results of analysis of two-neutron correlations in the region of small relative velocities are presented. The influence of spurious correlations on the form of correlation function is considered in detail. Data analysis and computer simulations were performed for a specific detector configuration with close angular position and different distances between the target and detector modules. The features of different methods of cross-talk elimination are examined. The proposed method is verified and the first results of cross-talk free correlation functions are presented for the Ar-Au reaction at 60 MeV/u measured with the DEMON detector at GANIL. © 1998 Published by Elsevier Science B.V.
