Abstract
Two boron trifluoride proportional counters, one containing normal isotopic boron and the other containing boron enriched to 96% B10, have been irradiated with 4.87-Mev. neutrons from the reaction D(d, n)He3. In addition to the reactions B10(n, α)Li7 and B10(n, α)Li7* with Q-values of 2.79 Mev. and 2.31 Mev. respectively, two other reactions have been observed. These are (i) F19(n, α)N16* with a Q-value of −1.77 ± 0.15 Mev. and (ii) either B10(n, p)Be10 or, much more probably, B10(n, t)Be8 with a Q-value of 0.35 ± 0.20 Mev. Owing to the presence of these two reactions, the analysis of complex fast-neutron spectra by the use of such counters is not feasible.
