Neutron Capture Measurements on Fission Product ¹⁰⁷Pd

Neutron capture measurements were made on a sample of fission product palladium at the Oak Ridge Electron Linear Accelerator time-of-flight facility. One hundred thirty resonance peaks were parameterized up to 3.5 keV and the average cross section from 3 to 600 keV was derived. The data exceed the ENDF/B-Vevaluation by ∼25% in the 3- to 300-keV range but drop steeply below it at higher energies where neutron inelastic-scattering competition becomes important. The Maxwellian average cross section for kT = 30 keV is calculated as 1.34 ± 0.06 b, and the dilute resonance capture integral as 108.1 ± 4.3 b.
