Abstract A method for the determination of Hf in an Yb matrix using the reaction176Hf(α, 3n)177W is described. The excitation function of this reaction was measured and the4He ion energy of 36 MeV was chosen.177W was determined by γ-spectrometry after chemical isolation by means of extraction chromatography with tri-n-butyl phosphate. Calibration measurements were carried out with known quantities ofnatHf. The sensitivity limit obtained was at the level of 3·10−8 g/g. The Hf admixtures innatYb and176Yb samples were estimated quantitatively.
