摘要：

The Feynman-Dyson perturbation theory is applied to Schwinger's model of the monopole. The propagator for photon exchange between electric and magnetic charges is found to be DABμν(k)=(k2+iε)-1×(εμνλκnλ kκ)(n•k). [In the frame of quantization, n=(0,n^), where n^ is the unit vector in the direction of the singularity line.] Since the exact theory is independent of n, one might try to obtain a manifestly covariant perturbation expansion by averaging over all directions of n. Under such a procedure the Born term reproduces the known nonrelativistic limit, if proper care is taken of the helicity-flip phase factor. © 1969 The American Physical Society.
