  Estimated cross sections for neutron production from triton bombardment of
gold are deduced from measurements of triton interactions with gas targets that
used gold as a triton beam stop material. Differential cross sections for
production of neutrons from 5.97-, 7.47-, 10.45-, 16.41- and 19.14-MeV tritons
on 197Au were evaluated. Corrections for the neutron interaction in gold, in
the target structure and in the air of the flight path were obtained by means
of a Monte Carlo technique. Uncorrelated scale uncertainties range from 24 to
41% whereas those of double differential cross sections range from 0.2 to 5%.
Based on these cross section data, calculation of neutron yield at 0o from
fully stopped tritons at 20.22 MeV agree with an independent measurement.
Least-squares fits with a gamma distribution model indicate an anisotropy in
the high energy portion of the neutron spectra. Legendre polynomial fits of
differential cross sections are reported. All neutron cross section data are
made available through the Experimental Nuclear Reaction Data (EXFOR) library
at international data centers.
