Abstract
Using the current value for the pion lifetime, we have recomputed the branching ratio for decay obtained from the 1963 experiment of Di Capua et al. and find , a change of 2%. The theoretically predicted value lies within two standard deviations, compared to the ½ standard deviation reported previously.
