Spectral lines spectrochemical series

Ion Beam Spectrochemical Analysis. As remarked earlier, ion irradiation of a surface produces visible light photons as well as many other types of particle. The light emission arises from the deexcitation of ions and excited neutrals, and is characterized by a spectrum consisting of a series of sharp lines at wavelengths associated with the type of ionized or excited atom. Spectral analysis thus provides elemental identification by reference to standard emission wavelength tables.
