Average energy of delayed neutrons from individual precursors and estimation of equilibrium spectra

In this paper, the available data on average energies from individual precursors are compiled. These data are used to calculate average energies for the six half-life groups using a simplified version of the technique of Saphier et al. Also examined is whether the average energy can be applied in a one-parameter formula to approximate the delayed neutron spectra for individual precursors, six-group, or equilibrium conditions. 29 refs
