Bremsstrahlung is a German term that means "braking rays." It is an important phenomenon in the generation of X-rays. In the Bremsstrahlung process, a high speed electron travelling in a material is slowed or completely stopped by the forces of any atom it encounters. As a high speed electron approaches an atom, it will interact with the negative force from the electrons of the atom, and it may be slowed or completely stopped. If the electron is slowed down, it will exit the material with less energy. The law of conservation of energy tells us that this energy cannot be lost and must be absorbed by the atom or converted to another form of energy. The energy used to slow the electron is excessive to the atom and the energy will be radiated as x-radiation of equal energy.
My question is about the energy lost by the electron, once it's transmitted from the electron and before its absorbed or transformed, what is the initial form of it?? I think that it were kinetic energy transformed to a mechanical energy causing other electrons in the atom to change their state energy and by that a photon is emitted by stimulation and this photon is the xray, am I right??
