Pion and kaon emission from the fireball formed in Ne + NaF collisions at 1-2 GeV/nucleon
Abstract
Double differential cross sections for proton, π+ and K+ meson production have been measured in Ne + NaF collisions at 1 and 2 GeV/nucleon. Parameterizations of the meson spectra with Maxwell-Boltzmann distributions yield common inverse slope parameters for kaons and high-energy pions at each beam energy. No evidence for different freeze out temperatures can be deduced from the spectral slopes of the emitted particles.
