The inelastic scattering of 14.1 MeV neutrons off magnesium nuclei is studied at the TANGRA facility using tagged neutrons and an ING-27 standard neutron generator. The energies and partial cross sections of visible γ transitions induced in different reactions between neutrons and magnesium nuclei are determined. The measured angular distribution of γ quanta for 24Mg is analyzed and compared to results from other experimental studies.

The results obtained by measuring the angular and energy distributions of gamma rays produced in reactions induced by the inelastic scattering of 14.1-MeV neutrons on$^{27}$Al nuclei are presented. The respective measurements were performed by the tagged-neutron method in a beam from the ING-27 compact neutron generator. The angular distributions were obtained for gamma rays emitted from the 844-keV 1/2$^{+}$, 1015-keV 3/2$^{+}$, 2212-keV 7/2$^{+}$, and 3004-keV 9/2$^{+}$ states of$^{27}$ Al nuclei.

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.

The results obtained by measuring the angular and energy distributions of gamma rays originating from the inelastic scattering of 14.1-MeV neutrons by carbon and oxygen nuclei are presented. The measurements in question were performed by the tagged-neutron method in a beam of an ING-27 standard portable neutron generator. The angular distributions of gamma rays emitted by the 2+ state of 12С at 4.43 MeVand the 3− state of 16O at 6.13 MeV were obtained.

The characteristic gamma radiation from the interaction of 14.1 MeV neutrons with a natural silicon sample is investigated with Tagged Neutron Method (TNM). The anisotropy of gamma-ray emission of 1.779 MeV was measured at 11 azimuth angles with a step of ∠15°. The present results are in good agreement with some recent experimental data.
