Abstract
In a set of ${\mathrm{B}}^{10}$-loaded C-2 emulsions exposed to eight neutron energies in the range 6-20 Mev, 1541 three-prong stars were found which were caused by either the ${\mathrm{B}}^{10}(n, t2\ensuremath{\alpha})$ or the ${\mathrm{B}}^{10}(n, d{n}^{\ensuremath{'}}2\ensuremath{\alpha})$ reaction. The triton cross section at 14 Mev is 102\ifmmode\pm\else\textpm\fi{}17 mb and decreases with increasing bombarding energy, while the deuteron cross section is 128\ifmmode\pm\else\textpm\fi{}19 mb and increases slightly with energy. The triton reaction proceeds partially through the 4.61-Mev state in ${\mathrm{Li}}^{7}$ and partially as a three-body breakup. In the deuteron reaction the following intermediate nuclei are formed: ${\mathrm{Be}}^{9}$, 2.43-Mev state; ${\mathrm{Be}}^{8}$, ground state and possibly the 2.9-Mev level; ${\mathrm{Li}}^{7}$, 10.8- and 12.4-Mev levels; and ${\mathrm{Li}}^{6}$, 2.19-Mev level. Four examples were found of the ${\mathrm{N}}^{14}(n, t3\ensuremath{\alpha})$ reaction. The feasibility of using the ${\mathrm{B}}^{10}(n, t2\ensuremath{\alpha})$ reaction as a neutron monitor is discussed.
