Relativistic theory of charge circulation in electron

The integrals of the Heisenberg motion equations of the zero-mass charge in electron are obtained by Dirac's method and analyzed. The charge is circulating along a circle with radius R=λ0(1 + α/π) and νφ=c=const. It is shown that spin s=h/2 and at the same time the full vector magnetic flow through the current circular contour directed opposite to spin |Φ| = Φ0 = πhc/e are quantized. The physical cause of the electron's magnetomechanical ratio - e/mc(1+α/π) doubling in comparison with the orbital one - e/2mc is found. The doubling is caused by the fact that about half the electron's mass, which is formed by the self stationary magnetic and electrostatic field, is not participating in spin generation. The product hν (ν - charge circulation frequency) is equal to electron rest energy to a high precision, and λ0=h/mc is equal to 2πR. (author)
