Plutonium oxide benchmark problems for the SOURCES code

Neutron yields and spectra for nine plutonium oxide (PuO2) compositions were calculated with the SOURCES 4C computer code. In addition to five experimental measurements serving as benchmarks for the SOURCES homogenous option, neutron production information for three postulated oxide compositions is also presented. Spectral information for neutrons originating from spontaneous fission and (α,n) reactions with light targets is presented in tabular format for further manipulation.
