Within systematic study of hadron production in nuclear collisions at the CERN SPS, the NA49 experiment registred data on C+C and Si+Si interactions at 40 and 158AGeV. The production of charged kaons in these reactions is a subject of this presentation.
The kaons were analysed and identified with the mean enegy loss dE/dx in the detector gas of the TPC’s. Fully corrected transverse mass and rapidity spectera of K+ and K meson will be shown. The energy and system size dependence of kaon multiplicity and the K to Pi relatins will be presented and discused. * Supported by BMBF and GSI.
