Input (English): The energy of this effect can be measured by the Chung-Jenkins formula. Semiconductor nanocrystals suppress this effect's namesake cooling in a temperature-dependent manner, while a nuclear version of it occurs in the decay of muonic lead-207 and bismuth-209. Another version produces spectator lines due to the creation of bound states, known as the "resonant Raman" version, while a specific version of it is the fast Coster-Kronig transition. In semiconductors, this effect is responsible for a three-particle recombination, while its inverse variety is called "impact ionization". KLL and LMM peaks are measured in a type of spectroscopy named for this effect, which was originally discovered in a cloud chamber. Originally discovered by Lise Meitner and competing with photon emission and electron capture, for 10 points, name this effect in which an electron is ejected from an atom as another electron fills the inner shell, named for a Frenchman.
