Using thermal neutron with Ekin = 25 meV hitting a Germanium crystal, I cannot reproduce the number quoted in table 1 of the paper arXiv:2011.13803 “Calibration of nuclear recoils at the 100 eV scale using neutron capture”. The table 1 is attached: in particular,
I don’t find the quoted branching ratio to single gamma from the compound nucleus.
Is there a way I can see what is actually used in the Geant4, and modify if needed ?
Thank you

At these energies, the best that Geant4 can offer is ParticleHP, with options use_only_photon_evaporation and do_not_adjust_final_state.
Here a macro for example Hadr03 (see PhysicsList.cc) and its printout.
In your table, I do not know exactly how column 5 is defined.
