New precise half-life for samarium-146 determined at 92 million years
Summary: Researchers from the Paul Scherrer Institute and the Australian National University have re-determined the half-life of samarium-146 to be 92.0 ±2.6 million years, resolving previous discrepancies in measurements. This precise value aligns with data from extraterrestrial samples, aiding astrophysicists and geochemists in dating planetary formation. The study, published in *Scientific Reports*, addresses long-standing uncertainties in the field.
