The angular distributions of scattered neutrons in the n + 12C reaction are measured at an initial neutron energy of 14.1 MeV for the cases of elastic scattering and inelastic scattering to the first excited state (JP = 2+, E1=4.44 MeV) of 12C nucleus. The experiment was carried out within the framework of the TANGRA (TAgged Neutron and Gamma RAys) project, based at the Frank Laboratory of Neutron Physics of Joint Institute for Nuclear Research. To register neutrons, 20 plastic detectors were used, scattered neutrons of different energies were separated by the time-of-flight technique. The collected data were corrected using a Monte Carlo simulation of the experiment to take into account multiple scattering in the sample and the finite size of the detectors. The resulting angular distribution was normalized to the experimental data of other authors to obtain the absolute values, the differential scattering cross section.
