Mass number dependence of activation capture cross sections for 14 MeV neutrons

Exciton model comparison of the activation and the integrated 14 MeV neutron radiative capture cross sections

“…Their uncertainties are less dependent on the experimental conditions than that of the flact data, in which the contribution of neutrons, degraded in energy, is not easily eliminated [2][3][4][5]. It was the contribution of these neutrons, which caused some older flact values to exceed the o-i,t data by more than a factor of 10, [6], while it was expected from simple arguments that o-act ~-~ flint" Recent measurements of flact confirm these expectations.…”

“…In addition, the chamber and its Ganges were constructed entirely of aluminum, which has a lower cross section for background (n, y) reactions than iron or copper [13]. The curves through the data are peak fits obtained using the maximum-likelihood method of Awaya [24].…”
