Abstract
The half-life of $^{6}\mathrm{He}$ has been measured using a low-energy radioactive beam implanted in an ${\mathrm{YAlO}}_{3}$ Ce-doped inorganic scintillator and recording decay events in a $4\ensuremath{\pi}$ geometry. Events were time-stamped with a digital data acquisition system enabling a reliable control of dead-time effects and detector gain variations. The result, ${T}_{1/2}=(807.25\ifmmode\pm\else\textpm\fi{}0.{16}_{\mathrm{stat}}\ifmmode\pm\else\textpm\fi{}0.{11}_{\mathrm{sys}}$) ms, provides the most precise value obtained so far and is consistent with the only previous measurement having a precision smaller than 0.1%. This resolves the long-standing discrepancy previously observed between two sets of measurements.
