Description

High resolution studies of a0/f0(980) decays into channels involving open strangeness are currently being performed at COSY-Juelich. As a 'filter' for isospin-zero intermediate states, i.e. to selectively produce for f0(980) resonance, the dd→αK+K- reaction was measured with the magnetic ANKE spectrometer. In order to determine the luminosity of this experiment, the elastically and quasi-elastically scattered deuterons were recorded simultaneously with the αK+K- events. Here we report about the luminosity determination via investigating the (quasi-) elastic deuterons at ANKE. (authors)
