Source sentences:
text: If the electron is accelerated in the electrostatic field around a nucleus, the resulting radiation is called bremsstrahlung ; it is synchrotron radiation (sometimes also called cyclotron radiation) when the acceleration takes place in a static magnetic field; and the process is called or Compton scattering (sometimes also called Thomson scattering) when the acceleration occurs in the electromagnetic field of a photon
