In this paper, we present results on transverse mass spectra and Hanbury Brown and Twiss correlation functions of negatively charged hadrons, which are expected to be mostly pi(-), measured in Pb-Pb collisions at 40 A GeV/c beam momentum. Based on these data, the collision dynamics and the spacetime Kextent of the system at the thermal freeze-out are studied over a centrality range corresponding to the most central 53% of the Pb-Pb inelastic crosssection. Comparisons with freeze-out conditions of strange particles and HBT results from other experiments are discussed.
