   <hidden TTP96-16  Hyperfine interactions between electrons > The relativistic Breit Hamiltonian between electrons is transformed into
 an effective vector potential ${\bf A}_i$ for the $i.$th
 electron, ${\bf A}_i$ having the structure of a recoil--corrected
 hyperfine operator.
  Apart from a small three--body operator, the Dirac--Breit equation
