Abstract: Abstract: The total cross section of the reaction has been measured at excess energies and 28 MeV with the magnetic spectrometer COSY-11. The new data show a significant enhancement of the total cross section compared to pure phase space expectations or calculations within a one boson exchange model. In addition, we present invariant mass spectra of two particle subsystems. While the system is rather constant for different invariant masses, there is an enhancement in the system towards lower masses which could at least be partially connected to the influence of the resonance.
