摘要	The isotope abundance ratio of lithium in the Li isotopic reference material IRMM-016 was redetermined by thermal ionisation mass spectrometry by means of synthetic isotope mixtures. This resulted in an absolute ratio n(Li-6)ln(Li-7) of 0.08212 +/- 0.00028, and corresponding isotope abundances of 7.589 +/- 0.024 amount % Li-6, 92.411 +/- 0.024 amount % Li-7 and an atomic weight of lithium of 6.94005 +/- 0.00024. Uncertainties are expanded uncertainties using a coverage factor of two. (C) 1997 Elsevier Science B.V.
