By the early 1970s, this detector was firmly established in the field of x-ray spectrometry and was applied as an x-ray detection system for SEM and x-ray spectrometry. The Si(Li) detector provides excellent resolution.
http://www.wikiradiography.net/page/Characteristics_and_Production_of_X-rays 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. For example, EK-alpha=(3/4)Ry(Z-1) =(10.2 eV)(Z − 1) , where Z is the atomic number and Ry is the Rydberg energy. The energy of the iron (Z = 26) K … Meer weergeven
