The neutron capture width of the 27.7-keV s-wave resonance in 56Fe has been determined using a setup completely different from most of the previous experiments. A pulsed 3-MV Van de Graaff accelerator and the 7Li(p,n) reaction served as a neutron source. Capture gamma rays were observed by a Moxon-Rae detector and gold was used as a standard. The samples were positioned at a flight path of only 7.6 to 8.0 cm. This allowed the use of very thin samples avoiding large multiple scattering corrections. Three metallic disks enriched in 56Fe were used with a thickness between 0.6 and 0.15 mm. Events due to capture of resonance scattered neutrons in the detector or surrounding material were completely eliminated by time-of-flight. The result for the capture width is Γγ = 1.01 eV with a statistical uncertainty of 1.3% and a systematic uncertainty of ∼5%.
