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?

    :eynman:

    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 !
