- Аннотация: The production of an electron-positron pair by two circularly polarized photons in an external crossed field is investigated. It is shown that in a weak field the total cross section is determined not only by the perturbation-theory series but also by the oscillating terms. The dependence of the cross section on the photon energy is found. The conditions under which the effect of an external field can be observed are indicated.
