B Question about x-ray, concept confusion

  1. Nov 5, 2016 #1
    1. Must the electron brought to rest(in one step or many steps) in Bremsstrahlung effect?
    2. Besides from a coming electron knocking off an electron on the shell then another electron fills the void, can the coming electron just excite an electron on the shell to a higher state and release a photon by the electron falling to a lower energy level?

    It gets slower, after a few interactions this typically means the electron is slow. It can also leave the material and fly away, however.
    Yes, but that process is very unlikely, and indistinguishable from free electrons falling in in most setups.
