Abstract
A new measurement of subthreshold and production is presented. The experimental data complete the measurement of strange particles produced in collisions at 1.9 GeV measured with the FOPI detector at SIS at GSI (Darmstadt). The yield ratio is found to be and is in good agreement with the transport model prediction. These measurements provide information on the in-medium cross section of - fusion, which is the dominant process in subthreshold production.
