Abstract

A procedure to enrich the natural 41Ca abundance in calcium by variable amounts was developed at the GSI medium-current mass separator. The method was applied to increase the natural 41Ca Ca ratios in three samples of modern deer bone, which were subsequently measured by accelerator mass spectrometry at the Rehovot 14UD Pelletron tandem accelerator. The following enrichment factors and original 41 Ca Ca ratios were measured for three bone samples, which all originate from approximately the same region in Germany: (i) 24.9 ± 1.3, (1.8 ± 0.7) × 10-14; (ii) 48.4 ± 2.4, (2.4 ± 0.6) × 10-14; (iii) 49.3 ± 2.5, (5.7 ±1.1)×10-14 41Ca Ca ratios lie at the upper end of terrestrial values measured in various bone samples at other laboratories. The measured ratios altogether spread over two orders of magnitude.
