Abstract
The positron-hydrogen atom and the positron-positive helium ion scattering problems at the energies below the second excitation threshold of the positronium are solved by the potential splitting approach combined with the complex scaling technique. We solve the Schrödinger equation in the total angular momentum representation. The elastic scattering and excitation cross-sections are obtained.
