For electron-atom ionization (e,2e), the importance of the final state
electron-electron interaction 
has been well established for ionization of hydrogen. To properly include
this effect, the final state 
wavefunction must include the Coulomb interaction between the two outgoing
electrons. We report 
here the first distorted wave calculation for ionization of heavy atoms
which contains the Coulomb 
distortion factor and which asymptotically is a proper solution of the three
body problem.
