Query: Role of breakup processes in deuteron-induced spallation reactions at
  100-200 MeV/nucleon   Use of deuteron-induced spallation reactions at intermediate energies has
recently been proposed for transmutation of several long-lived fission products
(LLFPs). In the design study of a transmutation system using a deuteron primary
beam, accurate cross section data of deuteron-induced reactions on the LLFPs
are indispensable. Reliable model predictions play an important role in
completing the necessary cross section data since currently available
experimental data are very limited. Under the circumstances, we have been
developing a code system dedicated for deuteron-induced reactions, which is
called DEURACS. Aiming to predict the production cross sections of residual
nuclei, the purpose of the present work is to clarify a role of deuteron
breakup processes in deuteron-induced spallation reactions at intermediate
energies. Isotopic production cross sections of residual nuclei in the
deuteron-induced reactions on 93Zr and 107Pd at 100-200 MeV/nucleon are
analyzed using DEURACS, in which the breakup processes are explicitly taken
into account. The calculated cross sections are decomposed into individual
components corresponding to the absorption of either neutron or proton in the
incident deuteron, or the deuteron itself. The calculated cross sections
reproduced the experimental data well over a wide mass number range of residual
nuclei. From a component-by-component analysis, it was found that the
components of nucleon absorption have the significant contributions to the
production of residual nuclei. Consideration of the breakup processes is
essential to predict the production cross sections of residual nuclei in
deuteron-induced reactions. The framework of DEURACS is applicable to
deuteron-induced spallation reactions at intermediate energies.
