Abstract
Positron-hydrogen scattering has been studied using close coupling approximation (CCA) in the energy range 19.584–200 eV. The coupling scheme: H(1s), H(2s), H(2p), H(3d), Ps(1s) is used to study elastic, 1s–2s excitation and ground state capture cross sections. The effect of capture channel is found to influence the scattering parameters.
