Pair Production in a Strong Electric Field with an Account of the Coulomb Interaction

In the framework of the Dirac model of vacuum the creation of е+е− pairs in a constant and uniform electric field with allowance Coulomb interaction between е+ and е− is considered. The transmission coefficient via the energy gap deformed by external field and the electric fields of particles is calculated in the semiclassical approximation. The Sauter exponential factor is modified by the exactly calculated function G(y) accounting Coulomb interaction of particles and changes in the shape of the potential barrier.

Dependence on the wave length and the periodical electric field strength of the densities of particle number and energy of the created from vacuum particle-antiparticle plasma of the fermi and bose types had investigated. Analytical and numerical calculations had fulfilled in the leading approximation for the case of rather small fields in comparison with the Schwinger critical field Ec = m2/e.
