Abstract
We present phase space distributions and multiplicities of K_s16, K- and phi mesons produced in Ar_s16KCl reactions at a kinetic beam energy of 1.756 AGeV and measured with the HADES spectrometer. The inverse slope parameters and yields of kaons supplement the systematics of previous measurements. The percentage of K- mesons coming fromphi decay is found to be 18_s16- 7%.
