Direct measurement of the $$^{39}$$ 39 Ar half-life from 3.4 years of data with the DEAP-3600 detector

Abstract The half-life of $$^{39}$$ 39 Ar is measured using the DEAP-3600 detector located 2 km underground at SNOLAB. Between 2016 and 2020, DEAP-3600 used a target mass of (3269 ± 24) kg of liquid argon distilled from the atmosphere in a direct-detection dark matter search. Such an argon mass also...
