APPROXIMATE ANALYTICAL SOLUTION FOR 2 ELECTRONS IN THE CONTINUUM

In this work we construct a correlated double continuum wave function for the three-body Schrodinger equation valid for large interparticle distances. Genuine three-body effects are considered by taking into ac count a nondiagonal part of the Hamiltonian written in generalized par abolic coordinates. A solution is found in terms of the confluent hype rgeometric function of two variables Phi(2), with similar structure to the first-order Faddeev approximation. The use of such a solution see ms to introduce appropriately the interelectronic repulsion.
