Abstract
The total cross section has been measured absolutely over the range of neutron energies from 0.88 to 14.1 Mev, with errors varying from 11 to 18%. At its low-energy end, the curve joins smoothly with an extension of the curve of earlier data of Blair and Holland, for which the maximum neutron energy was 0.62 Mev. A log-log plot of for the present data shows a variation approximately as for the high-energy portion of the curve with a break to greater flatness at the lower energies, resulting in a broad hump in the cross-section curve at about 2 Mev. This hump is believed to be due to competition from deuteron-producing reactions.
