Narrow Results

The possibility to select reliably the diproton final state with small excitation energy with the ANKE spectrometer at COSY-Juelich provides a new tool to study hadron interactions at intermediate energies. In this case the final proton pairs are found presumably in the ¹S₀ state which simplifies significantly the theoretical analysis. This approach has been successfully applied to the reactions pd → {pp}_sn at high and low momentum transfer kinematics, as well as to the pp → {pp}_sπ⁰ and pp → {pp}_sγ processes.
