520 ▼a The continued success of nuclear forensic analysis relies on the development of new material and process signatures. However, the unique safety hazards and strict controls concerning nuclear materials and operations limit the practicality of exp
520 ▼a Neutron activation has an inherent neutron energy dependence, making nuclide production rates contingent on the neutron energy distribution. Activation calculations performed by hand and with the FISPACT-II code are compared against experiments
520 ▼a Gamma-ray spectroscopy with high-purity germanium (HPGe) detectors is the leading passive assay technique for radioactive samples, providing detailed qualitative and quantitative information while preserving sample integrity. A simple HPGe detec
520 ▼a Activation calculations were able to validate the critical assembly neutron energy distribution but showed significant errors in the Be converter model. Additionally, validation of activation calculations identified shortcomings in the 60Ni(n,p)
