Abstract：

High resolution studies of a₀/f₀(980) decays into channels involving open strangeness are currently being performed at COSY-J\"ulich. As a "filter'' for isospin-zero intermediate states, {i.e.} to selectively produce the f₀(980) resonance, the $\rm dd\to \upalpha K⁺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.
