High-accuracy Geant4 simulation and semi-analytical modeling of nuclear resonance fluorescence
Jayson R Vavrek, Brian S Henderson, Areg Danagoulian
Nuclear resonance fluorescence (NRF) is a photonuclear interaction that enables highly isotope-specific measurements in both pure and applied physics scenarios. High-accuracy desig…

Validation of Geant4's G4NRF module against nuclear resonance fluorescence data from U and Al
Jayson R Vavrek, Brian S Henderson, Areg Danagoulian
G4NRF is a simulation module for modeling nuclear resonance fluorescence (NRF) interactions in the Geant4 framework. In this work, we validate G4NRF against both absolute and relat…
