Abstract

Two experiments on the production of the a 0 + (980)-resonance in the reaction ppda 0 + were performed with the ANKE spectrometer at COSY-Jülich. The decay channels \(a_0^ + \to {K^ + }{\bar K^o}\) and a 0 + π + η were measured simultaneously at energies T = 2.65 GeV and T = 2.83 GeV. For the reaction \(pp \to d{K^ + }{\bar K^o}\) a total production cross-section of ~ 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 \(a_{_o}^ + \to {K^ + }{\bar K^o}/{\pi ^ + }\eta .\).
