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

Abstract

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.
