Characteristic X-rays can be used to identify the particular element from which they are emitted. This property is used in various techniques, including X-ray fluorescence spectroscopy, particle-induced X-ray emission, energy-dispersive X-ray spectroscopy, and wavelength-dispersive X-ray spectroscopy. Meer weergeven Characteristic X-rays are emitted when outer-shell electrons fill a vacancy in the inner shell of an atom, releasing X-rays in a pattern that is "characteristic" to each element. Characteristic X-rays were discovered by Meer weergeven Characteristic X-rays are produced when an element is bombarded with high-energy particles, which can be photons, electrons or ions … Meer weergeven K-alpha K-alpha emission lines result when an electron transitions to a vacancy in the innermost … Meer weergeven • Electron capture • Internal conversion Meer weergeven The different electron states which exist in an atom are usually described by atomic orbital notation, as is used in chemistry and general physics. However, X-ray science has special terminology to describe the transition of electrons from upper to lower energy … Meer weergeven The transition energies can be approximately calculated by the use of Moseley's law.
