Abstract

A generalized eikonal approximation in the relativistic quantum theory of Dirac particle scattering on an arbitrary electrostatic potential in the field of strong electromagnetic waves is developed. An analytic formula for the particle wave function is obtained. The essence of the approximation is that quadratic scattering potential terms $[\sim U^{2} (\vec{r})]$ are considered small.
