Hello,
I am doing a simulation of the low energy photoelectric effect, the energy of the gamma is around 8 eV, the material being irradiated is 20nm thick gold, using G4EmStandardPhysics, but no photoelectron production is observed.
I saw that SetLowestElectronEnergy and SetMinEnergy in the G4EmStandardPhysics function are both 100eV, so I set the Cut of gamma and e- to 0.1nm, but still no photoelectron production. However, in reality the work function of gold is around 5.1 eV, and a gamma of 8 eV is sufficient to produce the photoelectric effect. Is Geant4 not able to simulate such a low energy photoelectric effect?
Thanks
