In the Auger process an atom makes a transition to a lower state without emitting a photon. The excess energy is transferred to an outer electron which may be ejected by the atom. (This is called an Auger electron). Assuming the nucleus to be massive, calculate the kinetic energy of an n = 4 Auger electron emitted by Chromium by absorbing the energy from a n = 2 to n = 1 transition.

Question

Philoid · Accepted Answer

energy released during transition from n=2 to n=1,

Energy required to knock off electron from 4^th shell

Now the difference in the transition energy and energy required to knock off electron from 4^th shell will be seen as kinetic energy of electron,

(Z for chromium is 24 and from hydrogen atom )

∴

∴ K.E.=
