Abstract
Accurate knowledge of absolute delayed neutron yields ({nu}d) needs to be improved. A method to derive the anti{nu}d is to do a summation calculation using cumulative fission yields (CU) and delayed neutron branching (Pn) for all precursors. For the `CU` we have taken the data from the JEF-2 file for 3 fissile systems. We have also done the calculations with the `CU` distributed by Wahl for U233T, U235T and F, U238F, PU239T, PU241T. In JEF-2 we have `Pn` data for 156 precursors, almost 100 coming from experimental results and the others from a calculation by Klapdor. The results are compared with the last evaluations for the systems already measured. The relative uncertainty is three times higher for the `CU` than for the Pn.
