Methods to Collect, Compile, and Analyze Observed Short-lived Fission Product Gamma Data

Technical Report ·
DOI:https://doi.org/10.2172/1028568· OSTI ID:1028568
A unique set of fission product gamma spectra was collected at short times (4 minutes to 1 week) on various fissionable materials. Gamma spectra were collected from the neutron-induced fission of uranium, neptunium, and plutonium isotopes at thermal, epithermal, fission spectrum, and 14-MeV neutron energies. This report describes the experimental methods used to produce and collect the gamma data, defines the experimental parameters for each method, and demonstrates the consistency of the measurements.
