Abstract

High resolution neutron capture measurements of a highly enriched 208Pb sample were carried out at the Gelina pulsed neutron facility and the capture areas of twelve resonances in the range 1 - 400 keV were determined. From these values the Maxwellian-averaged cross-section <sigma> was calculated vs kT from 5 to 100 keV. After adding the estimated direct capture contribution, the results agree with those of previous activation measurements but are a factor of two lower than the Oak Ridge neutron capture data. The reason for such a discrepancy is highlighted in this report.
