Isotopic fractionation in meteoritic cadmium

Nature volume 261, pages 216–218 (1976)Cite this article

Abstract

ISOTOPE and elemental abundance studies of Cd in this laboratory have led to the discovery of Cd with an isotopic composition which differs significantly from that normally observed in nature. This isotope abundance study was initiated with the primary aim of detecting and measuring neutron irradiation effects in Cd (113Cd (n,γ) 114Cd, Σ = 20,000 barn) of similar origin to that observed in Gd (ref. 1), and included a survey of Cd isotope abundance in terrestrial samples2 and a range of meteorites. The meteorite data will be reported in detail elsewhere. The Brownfield H3 chondrite, included in the survey because of its enhanced Cd content3, was found to contain anomalous Cd; some results are given in Tables 1 and 2.
