We study positron-helium scattering using close coupling approximation (CCA) employing different combinations of the following basis functions: He(Isis), He(ls2s), He(ls2p), Ps(ls), and Ps(2s), where Ps stands for the positronium atom. We observe a prominent S wave resonance of width 2 eV at about 3

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
