WebIron has four naturally occurring stable isotopes: 54 Fe (5.84%), 56 Fe (91.76%), 57 Fe (2.12%), and 58 Fe (0.28%). Both 56 Fe/ 54 Fe and 57 Fe/ 54 Fe ratios are reported in the … Naturally occurring iron (26Fe) consists of four stable isotopes: 5.845% of Fe (possibly radioactive with a half-life over 4.4×10 years), 91.754% of Fe, 2.119% of Fe and 0.286% of Fe. There are 24 known radioactive isotopes, the most stable of which are Fe (half-life 2.6 million years) and Fe (half-life 2.7 years). … See more 1. ^ Fe – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 3. ^ # – Atomic mass marked #: value and uncertainty derived not from purely experimental … See more The isotope Fe is widely used in Mössbauer spectroscopy and the related nuclear resonance vibrational spectroscopy due … See more Iron-60 is an iron isotope with a half-life of 2.6 million years, but was thought until 2009 to have a half-life of 1.5 million years. It undergoes beta decay to cobalt-60, which then decays with a half-life of about 5 years to stable nickel-60. Traces of iron-60 have been found … See more Fe is observationally stable, but theoretically can decay to Cr, with a half-life of more than 4.4×10 years via double electron capture (εε). See more The isotope Fe is the isotope with the lowest mass per nucleon, 930.412 MeV/c , though not the isotope with the highest nuclear binding energy per nucleon, which is nickel-62. However, because of the details of how nucleosynthesis works, Fe is a more common … See more . See more • J. M. Nielsen (1960). The Radiochemistry of Iron (PDF).

Nonbiological Fractionation of Iron Isotopes Science
WebFor molten FeO, the fractionation factor is indistinguishable from the inverse square root of the mass of the evaporating iron isotopes (i.e., α = 54 / 56). The situation when iron evaporates from a silicate liquid with solar proportions of the major oxides (also shown in Figure 12 ) is quite different, even though the only component that ...
