Abstract
The half-life, the branching ratio, and the decay value of the superallowed emitter were measured in an experiment performed at the JYFLTRAP facility of the Accelerator Laboratory of the University of Jyväskylä. is the heaviest nucleus for which high-precision measurements of these quantities have been tried. The half-life ( ms) and the value [ keV] are close to or reach the required precision of about 0.1%. The branching ratio for the superallowed decay branch [], a by-product of the half-life measurement, does not reach the necessary precision yet. Nonetheless, these results allow one to determine the experimental value and the corrected value to be 3114(79) and 3122(79) s, respectively.
