The Breith-Wheeler resonant process has been theoretically studied in a strong X-ray electromagnetic wave field under conditions when the energy of one of the initial high-energy gamma quanta passes into the energy of a positron or electron. These resonant conditions have been studied in detail. Analytical formulas for the resonant differential cross-section of channels A and B of the reaction are obtained. It is shown that the resonant differential cross-section significantly depends on the value of the characteristic Breit-Wheeler energy, which is determined by the parameters of the electromagnetic wave and the initial gamma quanta. With a decrease in the characteristic Breit-Wheeler energy, the resonant cross-section increases sharply and may exceed the corresponding non-resonant cross-section by several orders of magnitude.
