Summary
The Green’s functions for charged particles of spin zero and 1/2 interacting with electromagnetic plane wave, expressed in the coordinate gauge, are calculated in the path integral framework using the delta-functional technique. It is also shown that in the case of spin zero, the semi-classical Green’s function is accurate.
