One of the outer electrons moves in to fill this hole and in the process emits an X-ray photon of characteristic wavelength. If the electron falls from the shell with n = 2 (called the L¡shell) into the K-shell we have the Kfi line of Fig. 2.1; if it falls from the shell with n = 3 (called the M¡shell) we have the Kfl line; and so on.
