Long-sought measurement of exotic beta decay in thallium helps extract the timescale of the Sun's birth
How long did it take our Sun to form in its stellar nursery? Scientists are now closer to an answer. They succeeded in the measurement of the bound-state beta decay of fully-ionized thallium ions at the Experimental Storage Ring (ESR) of GSI/FAIR. This measurement has profound effects on the production of radioactive lead in asymptotic giant branch (AGB) stars and can be used to help determine the Sun's formation time.
