The study of the dp→ppn reaction at 500 MeV of the deuteron energy at ITS Nuclotron

The experiment on dp non-mesonic breakup at Internal Target Station at Nuclotron-M is presented. The first results on the study of the dp -breakup reaction with 500 MeV unpolarized deuteron beam are discussed. Selection procedure of useful events for the d p → p p n reaction with the registration of two protons is shown.
