Abstract
The isotope abundance ratio of lithium in the Li isotopic reference ma terial IRMM-016 was redetermined by thermal ionisation mass spectromet ry by means of synthetic isotope mixtures. This resulted in an absolut e ratio n(Li-6)ln(Li-7) of 0.08212 +/- 0.00028, and corresponding isot ope abundances of 7.589 +/- 0.024 amount % Li-6, 92.411 +/- 0.024 amou nt % Li-7 and an atomic weight of lithium of 6.94005 +/- 0.00024. Unce rtainties are expanded uncertainties using a coverage factor of two. ( C) 1997 Elsevier Science B.V.
