Reeder, P L

This paper summarizes the techniques used to measure the delayed neutron emission probability and includes an evaluated list of all experimental values for fission product precursors. Various models and theories for calculating these probabilities are summarized. The application of estimated and experimental delayed neutron emission probabilities to the calculation of delayed neutron yields from fission is illustrated. Some suggestions for new and improved measurements are presented. Emission probabilities for non-fission product precursors are compiled in a separate table. The recently discovered processes of beta-delayed two-neutron and beta-delayed three-neutron emission are reviewed. 87 references.
