The Geant4 hadronic physics sub-library includes an extended set of models for highand low-energy hadronic interactions. We report on recent developments in the Geant4 nuclear de-excitation module, which is used by many Geant4 models to simulate the de-excitation of nuclear recoils produced in nuclear reactions. These processes significantly influence hadronic shower shape and energy deposition. We present the structure of the de-excitation module, and compare Geant4 predictions with thin-target experimental data, using different Geant4 hadronic physics models. These comparisons are performed for Geant4 version 11.3, which was publicly released in December 2024.
