Positron scattering by hydrogen atom is an interesting system to test theoretical methods due to its simplicity. Recently, theoretical calculations have reported differential cross sections (DCS) for positronium (Ps) formation for this system. The present work utilises the coupled-channel optical me

We study e+-Na, e+-K, and e+-Rb scattering using the close coupling approach in the static and coupled static expansion schemes. We calculate partial wave elastic scattering phase shifts and total elastic and Ps formation cross sections up to an incident positron energy of 100 eV. The effect of the
A multichannel theory for the positron annihilation above the positronium formation threshold based on the modified Faddeev equation is presented. Its relation with the one channel effective charge formula is discussed. Application to the positron-hydrogen scattering has been carried out. A number o
