THE NEUTRON CAPTURE CROSS SECTION OF 56-FE FROM 1 TO 350 KEV
The Geel capture data have been analyzed up to 350 keV using the shape programme FANAC and the area programme TACASI. The parameters of 115 resonances have been determined. The present Geel results are compared to previous data sets, with special emphasis put on the most recent works and on those performed with comparable resolution. Conclusions about the level of agreement of the different data sets are drawn. The experimental problems connected with the normalization of the capture data for structural materials are discussed. They are related to the discrepancy found between the resonances parameters (in particular GAMMA-n) of the 1.15 keV resonance derived from transmission measurements and those derived from normalizing the Fe capture data to saturated Ag or Au resonances. This problem has received international recognition with a setting up of a special Task Force by NEANDC. We try to assess quantitatively the systematic errors in the final data brought about by such a discrepancy.
