翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Photoionization ： ウィキペディア英語版 Photoionization Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule. ==Cross section== Not every photon which encounters an atom or ion will photoionize it. The probability of photoionization is related to the photoionization cross-section, which depends on the energy of the photon and the target being considered. For photon energies below the ionization threshold, the photoionization cross-section is near zero. But with the development of pulsed lasers it has become possible to create extremely intense, coherent light where multi-photon ionization may occur. At even higher intensities (around of infrared or visible light), non-perturbative phenomena such as ''barrier suppression ionization'' and ''rescattering ionization'' are observed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Photoionization」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
