For 6 Li the absorption cross section could be equated directly to the (n, α) cross section.In the case of 10 B, the absorption cross section may contain a weak component due to the (n, t) …

WebbMeasured angular distributions of tritons following the 6 Li (n,t)α reaction are reported for incident neutron energies between 0.19 to > MeV. The neutrons were produced by spallation at the WNR facility at the Los Alamos Neutron Science CEnter (LANSCE), with the incident neutron energy determined by the time-of-flight method.
