Query: Radiation Reaction and the Electromagnetic Energy-Momentum of Moving
  Relativistic Charged Membranes   The charged membrane of Dirac provides a stable electron model with finite
self energy. Its total mass $m$ has been previously calculated from the
Hamiltonian of the membrane. To complete the picture we evaluate it here on the
basis of the energy-momentum of its self field (radiation reaction) and obtain
the same result showing the consistency of the model. We show explicitly that
the old 4/3-problem does not arise. The electron's stability (the vanishing of
total ${T^{\mu \nu}}_{, \nu}$) is due to surface tension $\kappa$ of the
membrane, but the model is as simple as the point particle, with two parameters
$\kappa$ and $e$; the surface tension parameter $\kappa$ can be expressed in
terms of the mass $m$.
