It produces energies from 280 to 2100 electron volts, small enough that only surface atoms are involved in its namesake spectroscopy.
This phenomenon saps the recombination energy of photoluminescence centers in the impurity bands of semiconductors near band gap transitions by inducing phonon cascades, an effect also experienced in light-emitting diodes. Relative intensities it generates may be anomalously high due to associated Coster-Kronig transitions.(*) It has a higher probability of occurrence for light isotopes of heavy elements due to their propensity to undergo electron capture decay. Its quantification is given by 1 minus omega, or the fluorescent yield, which is the probability that an X-ray will be emitted instead of the occurrence of this effect. It produces energies from 280 to 2100 electron volts, small enough that only surface atoms are involved in its namesake spectroscopy. For 10 points, name this effect in which re-absorption of K-shell photons by outer-shell electrons results in the ejection of a secondary electron.
