Abstract.

Two experiments on the production of the a 0 + (980)-resonance in the reaction \(pp \to da_0^ + \) were performed with the ANKE spectrometer at COSY-Jülich. The decay channels \(a_0^ + \to K^ + \overline{K^0}\) and \(a_0^ + \to \pi^ + \eta\) were measured simultaneously at energies T = 2.65 GeV and T = 2.83 GeV. For the reaction \(pp \to dK^ + \overline{K^0}\) a total production cross-section of \(\sim 50\) nb has been deduced for T = 2.65 GeV. Further goals of the data analysis are to determine differential cross-sections like angular distributions and the branching ratio \(a_0^ + \to K^ + \overline{K^0}/ \pi^ + \eta\).
