Electrons may be ejected (i.e. removed to infinity as far as that atom is involved) from the inner energy shells, thus creating positive holes or vacancies. This electron leaves the shell with an energy equal to the photon energy less the K-shell electron-binding energy. Due to re-arrangement the positive holes may be filled by electrons from outer orbitals. Each time an electron is transferred the atom moves to a less energetic state and radiation is emitted at a wavelength corresponding to the difference in the energy between the initial and final states of the transferred electron. The energy in this way created is being released as a K-, L- or -M-Quant. The name depends on the energy level in which the hole is being filled up. For example, if a K electron is ejected and the hole is filled up by an L-electron the energy released will be equivalent to EK-EL.also called a Ka line. The L-vacancy may the
