dc.description.abstractWe critically evaluate the isovector GMO sumrule for the charged πNN coupling constant using recent precision data from π-p and π-d atoms and with careful attention to systematic errors. From the π-d scattering length we deduce the pion-proton scattering lengths 1/2(απ-p + απ-n) = (-20 ± 6(statistic)±10 (systematic)) ·10-4m-1πc and 1/2(απ-p - απ-n) = (903±14)·10-4m-1πc From this a direct evaluation gives g2c(GMO)/4π = 14.20 ± 0.07(statistic)±0.13(systematic) or f2c/4π = 0.0786 ± 0.0008.-
