Abstract

A new method, utilizing a modulated neutron source operated in antisynchronism with a long counter, has been used to measure the absolute and relative delayed-neutron yields of five fissionable isotopes for neutron-induced fission at 3.1 and 14.9 MeV. The results, in units of delayed neutrons per fission, for 14.9-MeV fission are: The measured ratios of delayed-neutron yields at 3.1-MeV to those at 14.9-MeV fission are: These new delayed-neutron yield data are in accord with qualitative theoretical predictions but are in marked disagreement with earlier measurements.
