abstract = {Relativistic electron diffraction depends on linear and
quadratic terms in the electric potential, the latter being
neglected in the frequently used relativistically corrected
Schrödinger equation. The quadratic electric potential term
modifies atomic scattering amplitudes in particular for
large-angle scattering and backscattering. The respective
correction increases with increasing scattering angle,
increasing atomic number and increasing kinetic energy.
Conventional tabulations for electron scattering and its
large-angle extrapolations can be amended in closed form by
a universal correction based on the screened Coulomb
potential squared.},
