✦ Synopsis
Scattering matrices in an adiabatic basis were calculated for a model two-state atomic collision using a simple modification (normalization of the wave function) of the Fox-Goodwin three-point recurrence rela tion. Unlike the previous application of this method to scattering the present algorithm was able to precisely calculate the scattering matrix not only at low collision energies (eV), but also at high energies (keV). An analysis of the convergence of the modified Fox-Goodwin algorithm is also discussed for several angular momenta and for several energies where the results were compared to the renormalized Numerov method.
