Abstract

The recent experiment with a new array detector aiming the investigation of halo neutron pair pre-emission in Si(Li11, fusion) is described. A new approach for testing the true nn coincidences against cross-talk has been worked out. An experimental evidence for residual correlation of the pre-emitted halo neutrons is presented. The results obtained in building the nn correlation functions by using the available denominators are discussed. A recent iterative method for calculation of the intrinsic correlation function was also applied. An experiment for precise measurement of the intrinsic nn correlation function is proposed.
