The field can be sufficiently strong so that gamma-rays passing near the imploded MBI core can be bent by the modification of the vacuum making transient gamma-ray lenses possible. At sufficiently high laser intensities the electrostatic fields could approach the Schwinger field. The substantial reduction of the pair creation threshold field from the vacuum in the finite volume of multiple focusing lasers has been shown previously. Here, we apply the same formalism to the Coulomb fields in the finite volume of the MBI to determine the probability of electron-pair creation verses initial density and cavity size., 2019 US-Japan Workshop on Theory and Simulations of High Energy Density Physics with Extreme Fields}, title = {Possibility for Pair Creation in Micro-bubble Implosions (MBI)}, year = {2019} }
