Resonances in positron scattering on a supercritical nucleus and spontaneous production of e+e- pairs

Published online: 31 October 2018
Solving the Dirac equation for a positron in the Coulomb field of a nucleus with Z > Zcr we observe (confirm) the resonance dependence of the scattering phase δx on the energy εp of the positron. A physical interpretation of these resonances is suggested.
