Title: Benchmarking of the SOURCES3A code for PuBe sources

Abstract

The SOURCES3A code calculates neutron production rates and spectra from ({alpha},n) reactions, spontaneous fission decays, and delayed neutron emission in homogeneous media, interface problems, and alpha-particle beams. SOURCES3A promises to be a very useful tool for generating the characteristics of unique sources for use in neutron transport calculations. A number of comparisons of SOURCES3A results with experiments for various source types were presented in Ref. 1. Here, additional spectral benchmarks with both experiments and other calculations for homogeneous PuBe{sub 13} sources are provided. Preliminary results for neutron production rates from Bu-Pe metal interfaces are also given. Note that SOURCES3A assumes that alpha-particle ranges are small relative to the dimensions of the materials.
