Parametrization of the statistical rate function for select superallowed transitions Academic Article uri icon


  • 2015 American Physical Society. We present a parametrization of the statistical rate function, f, for 20 superallowed 0+0+ nuclear transitions between T=1 analog states, and for 18 superallowed "mirror" transitions between analog T=1/2 states. All these transitions are of interest in the determination of Vud. Although most of the transition QEC values have been measured, their precision will undoubtedly be improved in the future. Our parametrization allows a user to easily calculate the corresponding new f value to high precision (0.01%) without complicated computing.
