A Shorter 146Sm Half-Life Measured and Implications for 146Sm-142Nd Chronology in the Solar System

N. Kinoshita, M. Paul, Y. Kashiv +16

The extinct p-process nuclide 146Sm serves as an astrophysical and geochemical chronometer through measurements of isotopic anomalies of its alpha-decay daughter 142Nd. Based on an…
