Delayed-neutron precursor data are being compiled in preparation of a new ENDF/B evaluation of delayed-neutron data. The probability of delayed-neutron emission, Pn, has been updated using ENDF/B-VM fission product yields and ENDF/B-V fission product decay data. Evaluations of 77 precursors are presented along with their effect on fission yields, Pn systematics, and calculational models.
