We investigate the reaction at COSY and SIS energies together with accompanying background reactions and inclusive particle yields. The a0+ is considered as a usual quark model state with two decay channels and . Calculated cross-sections for a0+ production as well as for the corresponding non-resonant channels and are compared. Especially, in case of the final channel , high statistics measurements are necessary to extract the a0+ signal from the high non-resonant background.
13.75.Cs - Nucleon-nucleon interactions (including antinucleons, deuterons, etc.).
13.25.-k - Hadronic decays of mesons.
