“…Covariance matrix of the generated cross section for reaction 9 Be(p,α) 6 Li. This is because the experimentalists actually measured the alpha-emission cross section, which also includes the contribution from the 9 Be(α,nα) 8 Be reaction, for which the cross sections start at 5 MeV. The reaction designation in EXFOR is incorrect.…”

“…Cross sections for reactions 9 Be(d,nγ) 10 B are available in the TENDL-2019 library [7] and the more recent library release TENDL-2021, which contains minor improvements for the reactions of interest. Cross sections for 9 Be(α,nγ) 12 C are found in TENDL-2021 and JENDL-5 libraries [8]. For the rest of the reactions listed above, the cross sections vary significantly between nuclear data libraries (if available at all) and often disagree with available experimental data.…”

To computationally support hydrogen and helium plasma discharges in the early stages of tokamak operation and to support the commissioning of the neutron detectors during these operational phases, creation of a realistic neutron and gamma ray particle source for Monte Carlo simulations will be needed. One of the most important parts of creating the particle source is calculating the reaction rates of the particle-emitting reactions to determine the emission profile in the plasma and the energy spectra of the emitted particles. In this paper the analysis and evaluation of cross sections for important neutron-emitting reactions, namely, 9Be(p,nγ)9B, 9Be(3He,nγ) 11C and charged-particle emission reactions 9Be(p,d)2α and 9Be(p,α)6Li that cause neutron emission in the next step of interactions are presented. The reaction cross sections were evaluated based on experimental measurements and empirical models describing the interaction of two charged particles. Evaluation of the associated uncertainties was also performed. The main goal of the work is to propose the newly evaluated cross sections for inclusion in the FENDL nuclear data library, thus making the cross section available to other researchers studying the above listed reactions.
