Auger effect

(ˈaʊɡə)
n
(Atomic Physics) the spontaneous emission of an electron instead of a photon by an excited ion as a result of a vacancy being filled in an inner electron shell
[C20: named after Pierre Auger (1899–1993), French physicist]

He interprets single maxima as lines of the discrete spectrum, much broadened due to the large probability of self-ionization (AUGER effect) ([p.sup.5])[.sub.1/2]nl [right arrow] ([p.sup.5])[.sub.3/2] + free electron.
Therefore we observe that if the dipole matrix element associated with the continuous spectrum is zero, we obtain as the absorption spectrum a line which is broadened due to the AUGER effect, and whose width is given by v = [2[pi][bar.q.sup.2]]/h, as expected.
