The transverse momentum and transverse mass distributions of negative hadrons and protons produced in high-energy nucleus-nucleus collisions are studied by a multisource ideal gas model. The calculated results are compared and found to be in good agreement with the NA49 experimental data of central Pb-Pb collisions at 158A GeV.
