Abstract

At the Kaon spectrometer KaoS at SIS/GSI, the production of kaons and antikaons in heavy-ion reactions at a beam energy of 1.5 A GeV has been measured for the collision systems Ni + Ni and Au + Au. The K − / K + ratio is found to be constant for both systems and as a function of impact parameter but the slopes of K + and K − spectra differ for all impact parameters. Furthermore, the respective polar angle distributions will be presented as a function of centrality.
