Characteristic Emission Spectra

  • Rudolf O. Müller

Abstract

X-rays are emitted when materials are irradiated by electrons or x-rays of sufficient energy. Systematic investigation of the emitted spectra was first carried out by Moseley (1913). He found that the spectra of the elements are rather similar and consist only of a very few lines; he also distinguished a K series and an L series (Figures 2.1 and 2.2). Moseley found a simple relationship between the wavelength of analog lines and the atomic number of the emitting element:
$$\mathop {\sqrt {\frac{1} {\lambda }} = propZ}\limits_{Z = atomicnumber} $$
