Abstract
The least-squaresS-wave phase shifts of the scattering of electrons by simple, Yukawa and static potentials are compared with the exact phases. Additionally,Kohn’s, Rubinow’s and the least-squares methods (LSM) are used for calculating theS-wave phase shifts ofe +−H elastic scattering by employing trial and test-function spaces which allow for virtual positronium excitation. The results are in good agreement with those of other authors.
