An electron in the K shell of Fe is ejected by a high-energy electron in the target of an x-ray tube. The resulting hole in the n = 1 shell could be filled by an electron from the n = 2 shell, the L shell; however, instead of emitting the characteristic Fe K_a x ray, the atom ejects an Auger electron from the n = 2 shell. Using Bohr theory, compute the energy of the Auger electron.
