Abstract
The resonance neutron capture cross section of 58Fe has been measured at the Oak Ridge electron linear accelerator with 0.2% energy resolution from 2.5 to 200 keV. Large corrections for scattered neutrons are required for the s-wave resonances which prohibit a study of correlation effects. The s- and p-wave radiative widths are Gamma gamma (s)=0.86+or-0.8 and g Gamma gamma (p)=0.58+or-0.06. Many new l>0 resonances are observed which have not been seen previously in transmission measurements. The Maxwellian averaged capture cross section at kT=30 keV is 15.9+or-1.5 mb.
