The thallium isotope composition of carbonaceous chondrites - New evidence for live ²⁰⁵Pb in the early solar system

Abstract:

The extinct radionuclide ²⁰⁵Pb, which decays to ²⁰⁵Tl with a half-life of 15 Ma, is of considerable cosmochemical interest, as it is the only short-lived isotope that is produced exclusively by s-process nucleosynthesis. Evidence for the existence of ²⁰⁵Pb in the early solar system has only recently been obtained from analyses of IAB iron meteorites, but significant uncertainties remain about the initial ²⁰⁵Pb abundance and Tl isotope composition of the solar system. In an attempt to better c...
