   I noticed, in a recent review of notes, that the mass term I defined was   
   NOT that of the electron, but rather the extrapolated   
   photocharge mass from an inelastic scattering model, found   
   to account for experimental data at optical energies from a   
   camera's output.  Pretty sure any mass works at the gamma-limit,   
   but haven't done the calculations.   
      
   As a point of clarification then, the photocharge mass is:   
      
   m = (m* - m_e),   
      
   where effective mass m* = m_e(1 + eta^2)^1/2;   
      
   m_e is electron mass and eta is electric field strength parameter[1]   
      
   eta = e( / (m_ewc)) = (gamma)(beta).   
      
   Here e is electron charge,  is r.m.s. electric field   
   strength and w is angular frequency.   
      
   I haven't re-computed for any other mass, and lazily   
   suspect the gamma-limit is generally sound for any   
   mass.  I'm presently lacking the fortitude to spelunk   
   into this conjecture to see why e.g. there would not   
   be an infinite spectrum of stable masses.   
      
   Maybe someone with a torch can say how deep this is.   
      
   That said, the salient point appears to be, at the gamma-limit:   
      
   m = E_n , c = (S)^1/2,   
      
   with E_n = 1/2(m_ev^2).   
      
   Mass as kinetic energy confined, liberated at the gamma-limit   
   with reduction of radius of confinement (like, in a collision).   
      
   Speed of light equal to square root of the constant scalar curvature.   
   I dunno.  This just makes for an intolerable neural itch.
