Angular momentum during bremsstrahlung

  1. Feb 10, 2016 #1
    Two free electrons approach each other, so they start to emit photons due to bremsstrahlung. Where does the angular momentum carried away by the emitted photons come from?

    I'm sure experts will jump on the phrasing 'start to emit photons' . Never mind. I suppose you googled ? I got lots of useful links.
    Angular momentum is conserved; the electron loses what the photon carries off (ahem...). The presence of another charged particle (normally a nucleus) that interacts through a virtual photon is essential ! There is no Feynman diagram for electron in, photon + electron out !
