Proton electron fusion

  1. Jan 26, 2009 #1
    Is this reaction possible , i mean bombarding a 1H target with an electron to form a neutron

    that's all what i want to know

    Not exactly. The reaction [itex]e + p \rightarrow n + \nu[/itex] can occur, but you need the outgoing neutrino. This would be called scattering and not fusion.

    Google 'inverse beta decay' and you'll find your answer. :smile:

    OK

    the reaction it self to be defined as fusion or electron capture that's the point
    I've read on wikipedia
    so the reaction p + e− → n + νe needs additonal energy to occur

    i .e the mass of electron and proton still needs about 782.33 KeV to yield a neutron and an electron antineutrino

    so the reaction can never generate energy as it is endothermic

    but can the energy of electron be used , i mean an electron of around 800 KeV hitting a proton would this yield a neutron?

    thanks alot

    The reaction can take place, if that is what you are asking.

    Ok but what's the mechanism?

    weak interaction, you got the hint "google 'inverse beta decay'"
