A consistent unified energy approach (operator perturbation theory) is used for numerical calculations of the electron‐positron pair production cross‐section in heavy nuclei collisions. Resonance phenomena in the nuclear subsystem lead to the structurization of the positron spectrum produced. The positron spectrum narrow peaks are treated as resonance states of the compound superheavy nucleus. Calculation results for the differential cross‐sections of the U‐U collision energies E1 (E1=162.0keV‐ third s‐resonance; E1=247.6keV‐ the fourth s‐resonance) are presented.
