Abstract
Prompt neutron capture from highly enriched samples of the stable silver isotopes was measured at the Oak Ridge Electron Linear Accelerator neutron time-of-flight facility. Resonance peaks were parameterized from 2.65 to 7 keV, and average capture cross sections were derived as a function of energy up to 2000 keV. The average values for the 109Ag(n,γ) cross section are a few percent smaller than for 107Ag up to 700 keV, above which energy they drop more rapidly, falling to ∼60% of the 107Ag(n,γ) cross section at 2000 keV Average radiation widths found for spin 1 resonances were 152 ± 7 meV for 107Ag and 146 ± 6 meV for 109Ag. Maxwellian average cross sections for kT = 30 keV are 801 mb for 107Ag and 778 mb for 109Ag with estimated uncertainties of 3%.Keywords
