Abstract

Two-particle correlation functions of negative hadrons over wide phase space, and transverse mass spectra of negative hadrons and deuteronsnear mid-rapidity have been measured in central Pb+Pb collisions at 158 GeV per nucleon by the NA49 experiment at the CERN SPS. A novel Coulomb correction procedure for the negative two-particle correlations is employed making use of the measured oppositely charged particle correlation. Within an expanding source scenario these results are used toextract the dynamic characteristics of the hadronic source, resolvingthe ambiguities between the temperature and transverse expansion velocity of the source; that are unavoidable when single and two particle spectra are analysed separately. The source shape, the total duration of the source expansion, the duration of particle emission, the freeze-out temperature and the longitudinal and transverse expansion velocities are deduced.
