| الوصف: | The production and the propagation of K +- and of K −-mesons in heavyion collisions at beam energies of 1 to 2 AGeV have systematically been investigated with the Kaon Spectrometer KaoS at the SIS at the GSI. The ratio of the K +-production excitation function for Au+Au and for C+C reactions increases with decreasing beam energy, which is expected for a soft nuclear equation-of-state. At 1.5 AGeV a comprehensive study of the K +- and of the K −-emission as a function of the size of the collision system, of the collision centrality, of the kaon energy, and of the polar emission angle has been performed. The K − /K + ratio is found to be nearly constant as a function of the collision centrality. The spectral slopes and the polar emission patterns are different for K − and for K +. These observations indicate that K +-mesons decouple earlier from the reaction zone than K −-mesons. PACS numbers: 25.75.Dw 1. |
