  • OT: beta decay in Thallium

    From Jan Panteltje@21:1/5 to All on Fri Nov 15 04:51:23 2024
    Long-sought measurement of exotic beta decay in thallium helps extract
    the timescale of the Sun's birth:

    Summary:
    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.

    That one is wonderful! Thanks Jan!

    A nuclear reaction where the energy difference is *so* tiny that fully
    ionising the element inside a star tips the balance between normal decay
    of neutral Pb205 decaying into Tl205 and Pb205 being formed from Tl205.
