Abstract
The isotopic composition of Te has been measured in a purified sample of interstellar microdiamonds from the Allende meteorite. Small positive anomalies were only found in 128Te (4.0 ± 0.3‰) and 130Te (9.3 ± 2.0‰) from three analyses of the Allende microdiamond sample EB#2. The magnitude of the anomalies are smaller than in the heavy noble gases, although the absolute amount of anomalous Te is greater than that of anomalous Xe in the same sample. The anomalies in Te can be interpreted in terms of standard r-process nucleosynthesis followed by rapid separation of the stable isotopes from their radioactive precursors.
