An 8-group representation of relative delayed neutron yields was obtained for epithermal neutron induced fission of 235U and 239Pu. These data were compared with ENDF/B-VI data in terms of the average half-life of the delayed neutron precursors and on the basis of the dependence of reactivity on the asymptotic period.
