Analytical expressions are derived for the asymptotic correlated three
-body state of a Coulomb compound consisting of a continuum particle a
nd an electron bound to a residual ion. The extension of these express
ions to finite distances is also given. The distortion of the continuu
m particle's motion by the Coulomb nuclear held and the field of the b
ound electron is investigated as well as the amount of polarization of
the bound system due to coupling of the bound electron to the continu
um particle.
