Design of a transportable high efficiency fast neutron spectrometer
2016, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :However the evaporation model underpredicts the 1–2% of decays that result in a single gamma ray at an energy near the Q value. The MENATE_R package [14,15] was used to simulate inelastic neutron carbon interactions. MENATE_R considers six inelastic reaction channels: (n,n'3α), (n,α), (n,n'p), (n,γ), (n,n'n), and (n,p) which were tuned to results from several experiments [16,17].
Method for measuring multiple scattering corrections between liquid scintillators
2016, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :The theory underlying the mass reconstruction assumes neutrons are only counted once, which is a correct assumption for 3He tubes. However, because fast neutrons can scatter multiple times between scintillators [5–8] and register artificially correlated counts, this traditional moment method unfortunately fails for scintillators. Using modified expressions for the moment method to theoretically account for multiple scattering, it was shown [9,10] that the calculated fractions of neutrons scattering multiple times can be used to apply corrections to the masses of nuclear materials undergoing fission.

2012, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :While this has proven useful for certain applications [12], cases where the simulated system is particularly sensitive to specific reaction channels require more realistic modeling. Therefore, the sparse but available experimental inelastic reaction data has been compiled for specific materials, such as carbon [13], allowing for models based solely on experimental cross-sections to be developed [1,4,14]. Comparison of the cascade models and the cross-section driven approaches at intermediate energies will continue to help advance our ability to accurately model neutron interactions.
