Investigation of the dp -Breakup Reaction at Intermediate Energies at Nuclotron

The studies of nuclear reactions involving deuterons play an important role in the understanding of the structure of the nucleons and the dynamics of nuclear interactions and helps to solve many actual relativistic problems of nuclear physics, such as nucleon-nucleon interaction at high energies, the structure of light nuclei at small inter-nucleon distances and the production of baryon resonances. Investigation of the deuteron-proton breakup reaction is one of the tools for studying the nature of 3NF and relativistic effects. The dp-breakup measurements have been carried out at the Internal Target Station at the Nuclotron in the framework of DSS project. The energy calibration of the Δ E - E detector has been performed at 300, 400, and 500 MeV. The S -curve for particular configurations obtained at 300 MeV of deuteron energy are presented.
