Neutron cross sections reported by various investigators often differ far in excess of the estimates of error reported. The high neutron emission of the High Energy Neutron Reaction Experiment HENRE source, 10 to the 13th power nsec, afforded an opportunity to compare measured values of many disintegration rates in a single experiment thus eliminating some of the uncertainty necessarily associated with such measurements when based on varying standards and normalizations. From these measurements, the 14.6 MeV neutron cross sections of 24 reactions are derived. The neutron spectrum near ground level at 37 feet slant range from the HENRE source was measured by using foil data and SAND II code.
