Measurement of the Differential and Total Cross-Sections of *g-Ray Emission Induced by 14.1 MeV Neutrons for C,Al,Si,Ca,Ti,Cr, and Fe Using the Tagged Neutron Method / P.S.Prusachenko, D.N.Grozdanov, N.A.Fedorov, Yu.N.Kopatch, G.V.Pampushik, P.I.Kharlamov, V.R.Skoy, I.N.Ruskov, T.Yu.Tretyakova, A.V.Andreev, C.Hramco, P.G.Filonchik. – Text : electronic // Chinese Physics C. – 2026. – Vol. 50, No. 3. – P. 034004. – URL: https://doi.org/10.1088/1674-1137/ae1cb1. – Bibliogr.: 95.
In this work, differential cross sections of *g-ray emission produced in nuclear reactions induced by 14.1 MeV neutrons are measured for the 4.439 MeV line from carbon, as well as for 10 individual *g-ray lines from aluminum, 6 from silicon, 8 from calcium, 16 from titanium, 6 from chromium, and 14 from iron. The measurements were conducted using the tagged neutron method with four LaBr&sub(3)(Ce) scintillation detectors positioned at angles of 25°, 45°, 60°, and 70° relative to the generator target – sample center axis. A neutron generator that can produce 16 separate beams of tagged neutrons was employed, which combined with the detector system, enabled the determination of differential cross-sections for 64 distinct angle values in the range of 17° to 89°. To simplify data visualization, the angular distributions were divided into 5° intervals, with weighted mean values of the angle and differential cross-section calculated for each interval. Corrections for multiple neutron scattering and attenuation, *g-ray attenuation, and total detection efficiency computed using GEANT4 were accounted for in the cross-section calculations. Additional measurements were performed to validate the correction calculations. The total *g-ray emission cross-sections were obtained by approximating the angular distributions with even-order Legendre polynomial expansions up to the 6th degree, followed by integration over the full solid angle. The total systematic error for the obtained data was estimated as 9.1%.
