It came back unexpectedly about two millennia later under the guise of the Zitterbewegung or trembling motion of the relativistic electron
that Erwin Schrodinger discovered in Dirac's theory of electrons and positrons.
In addition to this radiation zone, the craft found particles in the relativistic electron
radiation belt that have never been observed before and that researchers don't understand as of now.
Soon after Dirac presented his relativistic electron
theory, (6,7) O.

beam with ion-channel guiding," Physics of Plasmas, vol.
In this paper, the authors study a relativistic electron
coupling to a homogeneous magnetic field.
The relations in (1) also lead to the relativistic electron
energy E = [square root of ([m.sup.2][c.sup.4] + [c.sup.2][p.sup.2])].
 proposed X-ray brachytherapy sources based on the interactions of the relativistic electron
beam of DPF with a high-Z target.
Lead author Richard Thorne, a distinguished professor of atmospheric and oceanic sciences in the UCLA College of Letters and Science, and his team's analysis reveals that scattering by intense, natural very low-frequency radio waves known as "chorus" in the Earth's upper atmosphere is primarily responsible for the observed relativistic electron
The Lagrangian function for the relativistic electron
motion, expressed in Cartesian coordinates ([bar.r] = x[??] + y[??] + z[??]), is 
If we supply energy to this relativistic electron
, its speed cannot increase (possibly only its wavelength decreases) and any acceleration will be zero.
