Density functional calculations of the ground-state energies of atoms and atomic lattices in very high magnetic fields have established the correct surface electric field boundary condition in radio pulsars. Electrons or positrons can be accelerated to energies of the order of 103GeV in the region of high parallel electric field formed by the sub-set of magnetic flux lines which intersect the light cyclinder and curve towards the rotation axis. The unidirectional lateral displacement of curvature radiation pairs from the emission flux line is a corollary of the curvature. It is shown that the large displacement of lower-energy photon conversion points solves the return-current problem. Zero net charge crosses the light cylinder. The return-current kinetic energy is consistent with the measured X-ray luminosities. The region of high parallel electric field, for positive corotational charge density, may be separated from the neutron star surface by a force-free region. Solutions are obtained for the position of the high-field region.
