- Аннотация: Spontaneous positron emission, caused by the supercritical Coulomb source with charge Z and size R, is explored in essentially nonperturbative approach with emphasis on the VP-energy E_{VP}, considered as a function of the Coulomb source parameters Z and R. The specific contribution to E_{VP}, which appears in the supercritical case due to direct Coulomb interaction between VP-charge densities ϱ_{VP}(r), is outlined and studied in detail. It is shown that after first levels diving into the lower continuum, this contribution to E_{VP}, being properly renormalized, turns out to be negative in contrast to the classical electrostatics and so could play an important role in spontaneous emission, especially for Z just above the first Z_{cr,1}. The additional problems of spontaneous emission, caused by the lepton number conservation, are also discussed.
