In recent years, research and development of intensive accelerator-driven neutron sources lead to renewed
interest in the study of deuteron-induced reactions.The neutron sources with deuteron-induced reactions
on light nuclei ( 7 Li, 9 Be, 12 C, etc.) are proposed for various neutron beam applications such as irradiation
testing of fusion reactor materials, boron neutron capture therapy (BNCT), and production of radioisotopes
for medical use. Thus, comprehensive nuclear data of deuteron-induced reactions over the wide incident
energy and target mass number ranges are necessary for accurate estimation of neutron yields and induced
radioactivity in the engineering design of accelerator-driven neutron sources. In the case where experimental
data are not available, theoretical model calculations play an important role in nuclear data evaluation.
To meet the request, a comprehensive code for nuclear data evaluation, CCONE [1], is extended so that
deuteron-induced reactions can be taken into account for energies up to 200 MeV. In the extension, we use
the continuum discretized coupled-channels (CDCC) theory for elastic breakup reaction and the Glauber
model for stripping reaction to continuum in order to investigate deuteron breakup processes over the wide
target mass number [2]. In addition, a DWBA approach is also used for stripping reaction to bound states
in the residual nucleus.Sequential particle emission from highly excited compound and residual nuclei is
calculated using conventional statistical Hauser-Feshbach and exciton models. The extended CCONE has
been applied to cross section calculations of (d,xn) and (d,xp) reactions[3,4,5]. Particularly a systematic
trend of nucleon production is investigated by paying attention to the dependences of target mass number
and deuteron incident energy. Moreover, activation cross sections for several structural materials, such as
Fe, Ni, Cu, and so on, are calculated and compared with available experimental data to demonstrate the
extended CCONE code.
