翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Isotopes of iron ： ウィキペディア英語版 Isotopes of iron Naturally occurring iron (Fe) consists of four isotopes: 5.845% of 54Fe (possibly radioactive with a half-life over 3.1×1022 years), 91.754% of 56Fe, 2.119% of 57Fe and 0.282% of 58Fe. There are 24 known radioactive isotopes and their half-lives are shown below. See (Brookhaven National Laboratory Interactive Table of Nuclides ) for a more accurate reading. Much of the past work on measuring the isotopic composition of Fe has centered on determining 60Fe variations due to processes accompanying nucleosynthesis (i.e., meteorite studies) and ore formation. In the last decade however, advances in mass spectrometry technology have allowed the detection and quantification of minute, naturally occurring variations in the ratios of the stable isotopes of iron. Much of this work has been driven by the Earth and planetary science communities, although applications to biological and industrial systems are beginning to emerge. Standard atomic mass: 55.845(2) u. ==Iron-54== 54Fe is observationally stable, but theoretically can decay to 54Cr, with a half-life of more than 3.1x1022 years via double electron capture (2β+). 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「Isotopes of iron」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.
