“…1, did not allow us to make an extended OMP analysis. On the other hand, while previous OMP analysis on 6,7 Li [4,5] and 27 Al [1,2] show that no global OMP describes reasonably well the elastic scattering data in the energy range up to 20 MeV, slight adjustment of Daehnick et al [6] parameterization led us to a good description of the data for the copper isotopes (Fig. 1).…”

“…The simultaneous analysis of the deuteron elastic scattering and induced activation appears essential for a consistent input of nuclear model calculations [2], a prime interest for the optical model potential (OMP) parameters being motivated by their further use in the calculation of deuteron interaction cross sections.…”

“…In order to calculate this enhancement, the inelastic breakup cross section, σ (p) BF , has been multiplied by the corresponding fraction leading to the above-mentioned reactions, e.g. CNR*09 σ (n,x) /σ Reaction , where σ Reaction is the total neutron reaction cross section and s stands for γ, p, or α outgoing channel [2]. A similar procedure has been followed in order to obtain the contribution to the (d, 2n) reaction cross section due to the protons which, following the breakup neutron emission, are absorbed in further interactions with the target nucleus.…”

“…Therefore the actual calculations and measured data for deuteron-induced reactions are less extensive and mature than for neutrons, so that improved model calculations and further measurements are needed if the deuteron libraries are to approach the standard of the established neutron ones. These requests motivated a former analysis of the deuteron elastic-scattering and reaction cross sections induced on 27 Al, at the incident energies from 3 to 60 MeV [1,2], and its extension for the Cu stable isotopes.…”

Abstract. An extended analysis of the nuclear reaction mechanisms involved in the deuterons interaction with 63,65 Cu is presented. First, the available elastic-scattering data analysis provided us the optical potential for reaction cross sections calculations. An increased effort has been devoted to the breakup mechanism, both the elastic breakup and the breakup fusion contributions to the different activation cross sections being carefully considered. Next, the direct reaction contributions through the one nucleon stripping reaction cross sections have been calculated. Finally, the pre-equilibrium and compound-nucleus cross-section calculation, corrected for the breakup and stripping decrease of the total reaction cross section, completed the deuteron activation cross-section analysis. The overall agreement between the measured and calculated deuteron activation cross sections proves the correctness of the nuclear mechanisms account.

The activities of the EUROfusion consortium on the development of high quality nuclear data for fusion applications include evaluations of deuteron induced reactions and related data libraries for needs of the DEMO fusion power plant and IFMIF-DONES neutron-source nuclear analyses. Molybdenum is one of the major constituents of the reference stainless steels used in critical components of these projects. While the TENDL deuteron data library was the current reference used by EUROfusion, need of its further improvement has already been pointed out. The weak binding energy of the deuteron is responsible for the high complexity of its interaction with nuclei, involving also a variety of reactions initiated by the nucleons following the deuteron breakup. Their analysis completed that of the deuteron interactions with Mo and its stable isotopes, from elastic scattering to pre-equilibrium and compound–nucleus reactions, up to 50 MeV. A particular attention has been paid to the breakup, stripping, and pick-up direct interactions which amount to around half of the deuteron total–reaction cross section. The due account of most experimental data has validated the present approach, highlighted some prevalent features, and emphasized weak points and consequently the need for modeling/evaluation upgrade.
