Abstract
The generating functional of all quantum Green functions in an external field is found. The Green function of a scalar particle in a constant and uniform external field is calculated with the help of modified perturbation theory. Its infrared asymptotics is studied. It is shown that an enhancement of the pole takes place, as in the vacuum case.
