Abstract
The logarithmic part of the Lamb shift, the contribution of the relative order {alpha}{sup 3}log(1/{alpha}) to the atomic state energy, is related to the usual infrared divergence. For positronium, the calculated logarithmic correction does not vanish only in n{sup 3}S{sub 1} states and constitutes 5/24m{alpha}{sup 6}log(1/{alpha})/m{sup 3}. Logarithmic corrections of the relative order {alpha}{sup 2}log(1/{alpha}) to the positronium decay rate are also of the relativistic origin and can be easily computed within the same approach. 31 refs.; 11 figs.
