I Electronuclear reaction

    Hi !

    I study nuclear reactions due to electron beam. In simulation (GEANT4), I note, whatever incident energy (10 MeV < E < 1 GeV), the primary electron is not absorbed and continues after the interaction.
    This is not the case for protonuclear, photonuclear or neutronuclear reaction...!
    What causes this difference ?

    Thanks in advance !

    Protons and neutrons can join a nucleus, photons can disappear. Electrons cannot - neglecting the weak interaction there will always be an electron around. It can get bound to one of the nuclei involved in the interaction, but that is a rare process.
