We report a calculation of the mα6lnα-1 contributions to the triplet-singlet splitting of the positronium ground state. Our result, Δν(α6lnα-1)=1/2mα6lnα-1=46 MHz, shifts the thνeoretical prediction from two standard deviations below to two standard deviations above the most recent experimental value.
