The reaction pp → {pp}sπ 0 , where {pp}s denotes a diproton, i.e. an unbound interacting proton pair in the 1S0 , state, was investigated in order to obtain a differential cross section dσ/dΩ at small angles in the energy range 1.6–2.4 GeV. This work is intended for the presentation of the main procedures in the processing of experimental data.
