Description
Due to its extremely high absorption cross-section for thermal neutrons, gadolinium is widely used for passive shielding, neutron tagging, or even medical applications. A neutron capture on gadolinium is followed by an $\sim$8 MeV gamma de-excitation cascade, which is usually easily detectable. In order to perform accurate Monte Carlo simulations for these purposes, the complex gamma cascades need to be well-known. In this talk, the de-excitation chains implemented in Geant4 v11.0.3 are compared to the accurate calculations done by Peter Grabmayr (1) in MAURINA as part of R&D for LEGEND.
