英文摘要	Gravimetric synthetic mixtures prepared from highly enriched isotopes of germanium in the form of oxides of well defined purity were used to calibrate a thermal ionization mass spectrometer. Measurements on natural germanium samples yielded an absolute isotopic composition of 20.38(10) at. % Ge-70, 27.34(9) at. % Ge-72, 7.75(5) at. % Ge-73, 36.71(9) at. % Ge-74, and 7.82(4) at. % Ge-76, and the atomic weight of germanium as 72.639(7) both with an uncertainty given on the basis of 95% confidence limit. No isotopic fractionation was found in terrestrial normal germanium materials. (Int J Mass Spectrom 189 (1999) 205-211) (C) 1999 Elsevier Science B.V.
