Wombacher F.; Rehkamper M.; Mezger K. (2004)Mass fractionation laws relate the fractionation factor αA for one isotope ratio to the fractionation factor αB for a second isotope ratio of the same element, with a fractionation exponent β such that αA = αBβ. The exponent ...

Halliday A.; Rehkamper M.; Der-Chuen L.; Wen Y. (1996)The W isotopic composition of the bulk silicate Earth (BSE) is chondritic within current analytical uncertainties, indicating that terrestrial core formation commenced more than 50 Myr after the differentiation of the ...

Fehr M.A.; Rehkamper M.; Halliday A.N.; Schonbachler M.; Hattendorf B.; Gunther D. (2006)Tellurium isotope data acquired by multiple-collector inductively coupled plasma-mass spectrometry (MC-ICPMS) are presented for sequential acid leachates of the carbonaceous chondrites Orgueil, Murchison, and Allende. ...

Rehkamper M.; Frank M.; Hein J.R.; Porcelli D.; Halliday A.; Ingri J.; Liebetrau V. (2002)Results are presented for the first in-depth investigation of Tl isotope variations in marine materials. The Tl isotopic measurements were conducted by multiple collector-inductively coupled plasma mass spectrometry for a ...

Rehkamper M.; Halliday A.N. (1999)The precision of Tl isotopic measurements by thermal ionization mass spectrometry (TIMS) is severely limited by the fact that Tl possesses only two naturally occurring isotopes, such that there is no invariant isotope ratio ...

Schonbachler M.; Lee D.C.; Rehkamper M.; Halliday A.N.; Fehr M.A.; Hattendorf B.; Gunther D. (2003)Isotopic anomalies in Mo and Zr have recently been reported for bulk chondrites and iron meteorites and have been interpreted in terms of a primordial nucleosynthetic heterogeneity in the solar nebula. We report precise ...
