Precision half-life measurement of Al25

A new precision half-life measurement of Al-25 was conducted using the TwinSol beta-counting station at the University of Notre Dame. The new measured value of t(1/2)(new) = 7.1657(24) s is in good agreement with the most recent measurement, while being 3 times more precise. Using these new measurements, an evaluation of the 25Al half-life has been performed, leading to an average half-life of t(1/2)(world) = 7.1665(26) s, which is 5 times more precise than it's predecessor and has a more satisfactory Birge ratio of 1.1. To aid in future measurements of correlation parameters, a new Fermi to Gamow-Teller mixing ratio. and correlation parameters for this mixed transition have been calculated assuming the standard model validity using the new world half-life.
