    "abstract": "We investigate the existence of the electric field reversal in the negative\nglow of a dc discharge, its location, the width of the well trapping the\nelectrons, the slow electrons scattering time, and as well the trapping time.\nBased on a stress-energy tensor analysis we show the inherent instability of\nthe well. We suggest that the Fermi mechanism is a possible process for pumping\nout electrons from the through, and linking this phenomena with electrostatic\nplasma instabilities. A power law distribution function for trapped electrons\nis also obtained. Analytical expressions are derived which can be used to\ncalculate these characteristics from geometrical dimensions and the operational\nparameters of the discharge.",
