“…In fact, the major underestimation of the experimental data by TENDL-2017 evaluation is just due to the overlooking of the key role of direct stripping process. Actually, this proof is just in line with the previous discussions of the (d, p) excitation functions for 51 V [6], 50 Cr [7], 58 Fe [8], 64 Ni [9], and 93 Nb [21] target nuclei, which show apparent discrepancies between the measured data and TENDL evaluations. The analysis of the 55 Mn(d, x) 54 Mn reaction [ Fig.…”

“…As stressed out in previous analyses of deuterons interacting with nat Fe [8], nat Ni [9], and nat Cr [7], the measured activation cross sections of 51 Cr residual nucleus is a cumulative process (see Fig. 18 of Ref.…”

“…Altogether, the sum of the five reaction contributions succeeded to describe the measured 55 Mn(d, pxn) 54 Mn cross sections along the whole energy interval. Moreover, the underestimation of the lowest-energy data by the TENDL-2017 evaluation could be just the effect of the (d, t) pick-up process overlooking as it was stressed out in previous analysis of deuteron interaction with nat Ni [9] and 93 Nb [21]. The new data measured in this work for 55 Mn(d, x) 51 Cr reaction are important for completing the 51 Cr excitation function at incident energies just above its effective threshold, while previous measurements covered higher energies from 22 up to 50 MeV [11,12] [ Fig.…”

“…The following input options of the TALYS-1.9 code have been used: (a) the OMPs of Koning-Delaroche [44], Daehnick et al [23], Becchetti-Greenlees [45], and Avrigeanu et al [46] for neutrons and protons, deuterons, tritons, and α-particles, respectively, (b) the back-shifted Fermi gas (BSFG) formula for the nuclear level density, (c) no TALYS breakup contribution, since the abovementioned BF enhancements is still under implementation in TALYS, and (d) the PE transition rates calculated by means of the corresponding OMP parameters also involved within BU, DR, and CN calculations, for a consistent use of the same common parameters within various mechanism models. One may note that the same PE option was used with previous similar analyses of deuteron interaction with V, Cr, Fe, Co, Ni, and Cu [6][7][8][9][10] leading finally to an improved agreement with the measured data.…”

“…In order to calculate the BF enhancement of, e.g., the (d, xn) reaction cross sections, the BF proton-emission cross section σ p BF should be (i) multiplied by the ratios σ (p,x) /σ p R , corresponding to the enhancing reaction, (ii) convoluted with the Gaussian line shape distribution of the BF-proton energy E p for a given deuteron incident energy E d , and (iii) integrated over the BF proton energy. Consequently, the BF-enhancement cross section has the form [8,9,33]:…”

Background: The scarce data systematics and complexity of deuteron interactions demand the update of both the experimental database and theoretical frame of deuteron activation cross sections. Various reactions induced by neutrons and protons following the deuteron breakup (BU) should be also taken into account. On the other hand, deuteron reaction cross sections recommended recently for high-priority elements are still based on data fit without predictive power.Purpose: Accurate new measurements of low-energy deuteron-induced reaction cross sections for monoisotopic ( 55 Mn) natural manganese target enhance the related database as well as the opportunity of an unitary and consistent account of the related reaction mechanisms.Methods: Activation cross sections of 54,56 Mn, and 51 Cr nuclei by deuterons on 55 Mn were measured at energies ≤20 MeV by the stacked-foil technique and high resolution gamma spectrometry at the U-120M cyclotron of CANAM, NPI CAS. Then all available data for deuterons on 55 Mn up to 50 MeV are analyzed paying particular attention to BU and direct reaction (DR) mechanisms.Results: Newly measured activation cross sections strengthen the deuteron database at low energies, at once with a consistent account for the first time of all available data.Conclusions: Due account of deuteron-induced reactions on 55 Mn, including particularly the new experimental data at low energies, is provided by a suitable BU and DR assessment.

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.

The evaluation and deduction of recommended cross section values allowing extension of the database to monitor energy and intensity parameters of charged particle beams is presented. Included are 53 charged particle (p, d, 3He, 4He) induced reactions on suited C, Al, Ti, Fe, Ni, Cu, Nb and Au targets. The new data allow more systematic simultaneous use of multiple reactions on the same target and promote the backings of electrodeposited and sedimented targets as monitoring aids. Where possible the energy range is extended to above 100 MeV. Integral yield curves over the studied energy range are derived and compared to experimentally measured yields at specific energy points. A comparison with the theoretical excitation curve prediction of the TALYS-code as available in the TENDL 2021–2023 libraries is shown.
