Abstract
Numerical stabilization procedures are developed for solving the coupled integral equations that arise in connection with the separable treatment of exchange interactions in electron-molecule scattering. Stabilization is important for maintaining numerical accuracy in treating target molecules that produce strong-coupling potentials, especially at low collision energies. The techniques we have developed are reliable and do not add significantly to the computation times.
