Calculation of single-photon exchange diagrams in the quasipotential approach by means of the polarization operator
N. E. Nyun'ko, Yu. N. Tyukhtyaev
Abstract:
The contribution to the hyperfine shift of the positronium ground level is calculated to order
$\alpha^6$ on the basis of an expression for the polarization operator deduced from a quasipotential
equation.
