Abstract
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.
