An investigation of inelastic scattering of 14.1 MeV neutrons on an iron sample was carried out using an improved TANGRA (TAgged Neutron and Gamma RAys) setup at JINR (Dubna). The yields of the occurring \(\gamma \)-transitions and anisotropy of the emitted \(\gamma \)-rays were measured using the tagged neutron method. The setup with a high-purity germanium (HPGe) detector was used to obtain the energy spectrum of \(\gamma \)-rays. The setup with 18 BGO scintillation detectors positioned in a circle around the sample was used to obtain angular distributions of \(\gamma \)-rays. A detailed \(\gamma \)-spectrum for \((n,X\gamma )\) reactions was obtained and the \(\gamma \)-ray angular distribution was measured for the 847 keV and 1238 keV \(\gamma \)-transitions. The distribution was fitted by Legendre polynomials up to fourth order and the angular distribution coefficients \(a_2\), \(a_4\) were extracted. A comparison with other published experimental results is given. Model calculations using computer code TALYS 1.9 were performed. The results of calculations are discussed in comparison with the obtained experimental data.
