In this work, the coupled-channel optical method (CCOM) is implemented in a study of positron-rubidium (Rb) scattering at intermediate and high energies. The CCOM provides a realistic calculation for positron-atom scattering where the ab-initio optical potential accounts for the omitted continuum effect in the scattering system. The integral, positronium (Ps) formation and total cross sections are compared to experimental and other theoretical data where available.
