Study of Reactions Induced by Fast Neutrons on $${}^{{10}}$$B Nucleus with Tritium Emission Using Coordinate Detector

The interaction of fast neutrons with the $${}^{10}$$ B nucleus at energies from 3 to 7 MeV is studied with the aim of isolating the reaction with the production of the $${}^{8}\textrm{Be}^{*}$$ nucleus in an excited state. This reaction stands out from the three-body reaction with the emission of triton and two $$\alpha$$ particles. Simulation of ionization losses of secondary $${}^{3}$$ H and $${}^{4}$$ He nuclei in solid and gas layers of position-sensitive multiwire detectors with sensitive sizes of both $$100\times 100$$ and $$50\times 50$$ mm $${}^{2}$$ showed that events are localized in different areas in diagrams plotted from losses in two gas layers. Experimental result, with $$100\times 100$$ mm $${}^{2}$$ detector showed the possibility of isolating a reaction with the emission of $${}^{3}$$ H and $${}^{8}\textrm{Be}^{*}$$ nuclei.
