Theory of Atomic Decay following Inner-Shell Ionization
We assume that the target consists of free non-interacting atoms. Inner-shell ionization by photons and charged particles leads to the emission of x-rays and electrons . This emission seems to be characteristic of the atoms in the sense that the energies of the individual lines are generally found to be independent of the excitation mode although the intensity distribution may be very different. Notable exceptions are the Auger electrons which are emitted with Doppler-shifted energies in heavy-ion collisions and molecular x-rays which are characteristic of the colliding complexes rather than of the target atoms or the projectiles .
