TL;DR: In this article, two-pion correlations from Pb+Pb collisions at 158 GeV/c per nucleon were measured by the NA44 experiment at CERN, and multidimensional fits characterized the emission volume, which was found to be larger than in S-induced collisions.
Abstract: Two-pion correlations from Pb+Pb collisions at 158 GeV/c per nucleon are measured by the NA44 experiment at CERN. Multidimensional fits characterize the emission volume, which is found to be larger than in {ital S}-induced collisions. Comparison to the RQMD model is used to relate the fit parameters to the actual emission volume. {copyright} {ital 1998} {ital The American Physical Society}

TL;DR: In this paper, the results of analysis of two-neutron correlations in the region of small relative velocities are presented and the influence of spurious correlations on the form of correlation function is considered in detail.
Abstract: 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 ArAu reaction at 60 MeV u measured with the DEMON detector at GANIL.
