Reactions with 14.1 MeV neutrons are interest for fundamental research in nuclear physics, especially on carbon. Due to the compactness and prevalence of modern neutron generators, reactions with neutrons of these energies have found wide application in applied work, for example, in elemental analysis. To conduct such studies and plan new experiments, the complete databases of nuclear data are needed. On the other hand, on the basis of experimental data obtained in the study of neutron-nuclear reactions, the parameters of theoretical models can be refined, which can subsequently be used to calculate the properties of other processes. However, the use of available experimental data to optimize model parameters is hampered by the fact that they are in a format that is inconvenient for automation. On the basis of the Frank Laboratory of Neutron Physics, the international project TANGRA is being implemented to study the scattering of tagged neutrons on atomic nuclei. For the purposes of the theoretical part of the project, the TALYS program is used. It has wide functionality, and also contains nuclear structure database and library of the nuclear reaction models parameters, based on the RIPL-3 library. The results of calculations usually have good agreement between calculation and experiment. To simplify access to the calculation results and the TALYS database, TalysLib is being developed.
