“…Thus, the absorbed proton or neutron following the deuteron breakup contributes to the enhancement of the corresponding (d, xn) or (d, xp) reaction cross-sections, respectively. The importance of the BF enhancement has been particularly found for the case of the second and third chanceemitted particle channels [19][20][21][22][23].…”

“…Thus, improvements in the nuclear model code capabilities to extend the evaluated deuteron-induced reaction cross-sections of Mn [22] and all stable isotopes of Zr [21] and 95−98,100 Mo [23], in view of a final work concerning natural Mo, have been considered by analyzing all data up to 50 MeV. A sample case is shown in Figure 1 for deuterons on the heaviest 100 Mo isotope.…”

“…The deuteron interaction with low-and medium-mass target nuclei, at incident energies below and around the Coulomb barrier, proceeds largely through stripping (d, p) and (d, n), pickup (d, t), and (d, α) DR mechanisms. Then, PE and CN become important at higher energies ( [21] and Refs. therein).…”

The nuclear data evaluation for deuteron-induced reactions and α-particle emission by neutron interactions is addressed within “Nuclear data for fusion technology, from basic research to full-scale applications.” The status and open questions related to these subjects in the area of nuclear data for fusion technology, specifically for the nuclear design of the ITER fusion device, the European DEMO fusion reactor, and the IFMIF-DONES Irradiation Facility, are briefly reviewed. A firm demand for accurate cross-sections of reactions induced by neutrons and deuterons exists, in this respect, within a more enlarged energy range up to 50 MeV than for fission applications. The current requirements are closely met by the TENDL Evaluated Nuclear Data Library, settled using the TALYS nuclear model code, which is one of the most widely used codes in basic research and applications including nuclear fusion technology. However, further improvement of this data library has recently been suggested, while, with respect to fission applications, not only the aforementioned energy range but also the diversity of nuclear data for fusion technologies is plainly stretched. Consequently, the progress of nuclear data activities conducted more recently on deuteron-induced reactions and α-emission by neutron interactions, throughout the European Fusion Program and subsequent to previous achievements within F4E and EUROfusion programs, is wholly summarized.

“…These potentials can provide a convenient average description of the overall trend of the interaction as a function of mass and energy and are the only option when the experimental data and a microscopic approach are not available for nuclides. As a result, many sets of global OMPs are widely applied to the relevant reaction models [23][24][25][26][27][28][29].…”

In the T-matrix form of transfer reaction, the optical model potentials (OMPs) are used to compute the scattering wave function and transition operator. For most cases, the elastic scattering cross sections, normally used to generate the OMPs, are not directly given in the same experiment. Then the global OMPs, which fit the experimental data over a broad mass and energy range, have been widely used in the theoretical calculations. Different sets of global OMPs with different parameter sets can reproduce the scattering cross section equally well within the uncertainty. Here, we apply different global OMPs to calculate the (differential) cross sections of (d, p) transfer reactions on target nuclei 12C, 48Ca, 124Sn and 208Pb at different energies. The results demonstrate that the effects of deuteron and nucleon global OMPs on transfer (differential) cross sections vary with energy and the target mass. Furthermore, the influences of the spin-orbit coupling term of deuteron and nucleon global OMPs on the transfer cross sections are not negligible.

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.
