Half-life and initial Solar System abundance of (146)Sm determined from the oldest andesitic meteorite
The formation and differentiation of planetary bodies are dated using radioactive decay systems, including the short-lived (146)Sm-(142)Nd (T(½) = 103 or 68 Ma) and long-lived (147)Sm-(143)Nd (T(½) = 106 Ga) radiogenic pairs that provide relative and absolute ages, respectively. However, the initial...
