Abstract

A half-life determination on Sm147 and Lu176 was made by the use of a liquid scintillation technique. In the lutetium sample a thorium contamination was found by analysis of the measured gamma-ray spectrum. After purification by ion-exchange no gamma-activity could be found beside the one due to Lu176. The half-life of Sm147 is found to be (1.04±0.03) × 1011 y, the half-life of Lu176 is reported as (2.18±0.06) × 1010 y.

      The compilation of the half-life data reported along with the indication of the used technique allowed us to draw some interesting considerations. Half-life values obtained after 1950, when experimentalists considered the isotopic percentage of 147Sm in natSm, are found to range between (104 ± 3) Ga (Donhoffer, 1964) and (125 ± 6) Ga (Beard and Wiedenbeck, 1954). Among such data, the highest value was found by using a proportional counter, whereas the lowest was obtained by using a liquid scintillation counter.

      Determinations of the λ176Lu have been made by decay-counting experiments and Lu–Hf dating of terrestrial and meteorite samples whose ages were independently determined (Fig. 1). Decay-counting λ176Lu determinations scatter around 1.8 × 10− 11 yr− 1 with significant outliers on the lower and higher sides (Brinkman et al., 1965; Donhöffer, 1964; McNair, 1961; Prodi et al., 1969; Sakamoto, 1967). The λ176Lu values that have been reported since 1972 fell within the range from 1.70 × 10− 11 yr− 1 to 1.95 × 10− 11 yr− 1 (Dalmasso et al., 1992; Gehrke et al., 1990; Komura et al., 1972; Nir-El and Lavi, 1998; Norman, 1980; Sato et al., 1983; Sguigna et al., 1982), but this range extends far beyond the required precision for both dating and isotopic tracer studies.
