Editing Alpha particle X-ray spectrometer (section)

== X-ray ==

The alpha particles are also able to eject electrons from the inner shell (K- and L-shell) of an atom. These vacancies are filled by electrons from outer shells, which results in the emission of a characteristic X-ray. This process is termed [[particle-induced X-ray emission]] and is relatively easy to detect and has its best sensitivity and resolution for the heavier elements.
