====== TTP96-12 BINARY BOOSTS ======
 
 
   <hidden TTP96-12  BINARY BOOSTS > The relativistic motion of an isolated two--body system  (bound or
 unbound) of given lab energy $K^{0}$  in QED is 
 separated into cms motion and
 relative motion. The relative motion equation ${\cal K}_{L}} \psi_{L}
 ({\bf r}_{L} ) =0$ contains the momentum eigenvalue ${\bf K}$ of the
 cms motion. It is greatly simplified by a binary boost to the
 atomic rest frame, where $K^{0}$ and ${\bf K}$ appear only in a 
 Lorentz--invariant combination. This boost is not a product of 
 single--particle boosts, which are useful only for perturbative 
 interactions. CPT--invariance is demonstrated, and orthogonality
