   Equation 2.8 addresses a conservation of momentum condition   
   in terms of wave vectors k:   
      
   k1 + k2 = k1' + k2' (conservation of momentum)   
      
   But surely superconductivity is an elastic condition   
   also requiring conservation of energy:   
      
   k1^2 + k2^2  = k1'^2 + k2'^2  (conservation of energy)   
      
   It is noted that the linear 'conservation of momentum'   
   does not generate the non linear 'conservation of energy',   
      
   This superconductor elastic requirement   
   can be mechanistically accomplished by assuming a hexagonal lattice   
   which has a real and reciprocal lattice identity.   
   and introducing a 'g' factor such that:   
      
   g(k1 + k2) = k1' + k2' (conservation of momentum)   
      
   k1^2 + k2^2  = g(k1'^2 + k2'^2)  (conservation of energy)   
      
   This superconductor mechanistic reasoning is developed in:

   and particularly equations 2.3.11 and 2.3.12
