Resonance State of Compound Superheavy Nucleus and Eppp in Heavy Nucleus Collisions

A consistent unified quantum mechanical and quantum-electrodynamical approach (operator perturbation theory and quantum-electrodynamical perturbation theory) is used for numeric calculation of the electron-positron pair production cross-section. 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 according to the ideas of Refs. [5, 6]. Calculation results for the differential cross-sections dσ(ɛs, E₁)/dɛs for U-U collision energies E₁ (E₁=162.0keV- the third s-resonance and E₁=247.6keV- the fourth s-resonance) are presented.
