Determination of the 14-Mev Li7 (n,n'a)T Cross Section from Sphere Multiplication and Transmission Measurements

By utilizing lithium spherical shell transmission and multiplication measurements, the Li7(n,n'y)Li7 and the He6-production cross sections, it is possible to deduce that the 14-Mev Li (n,n'a)T cross section is 325 ± 75 mb. A spectrum for neutrons degraded in energy between 0 and 12 Mev is also given.
