Spallation reactions: A successful interplay between modeling and applications

摘要: The spallation reactions are a type of nuclear reaction which occur in space by interaction the cosmic rays with interstellar bodies. first induced an accelerator took place 1947 at Berkeley cyclotron (University California) 200MeV deuterons and 400MeV alpha beams. They highlighted multiple emission neutrons charged particles production large number residual nuclei far different from target nuclei. In same year, R. Serber described two steps: fast one high-energy particle leading to excited remnant nucleus, second one, much slower, de-excitation remnant. 2010 IAEA organized workshop present results most widely used codes within benchmark models. If goals was understand deficiencies, if any, each code, remarkable outcome points out overall high-quality level some models so great improvements achieved since Serber. Particle transport can then rely on such treat between light atomic nucleus energies spanning few tens MeV up GeV. An overview modeling is presented order point incomparable contribution based basic physics numerous applications where occur. Validations or benchmarks, necessary steps improvement process, also addressed, as well potential future domains development. Spallation representative case continuous studies aiming understanding mechanism end powerful tool.
