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
Absolute tot.4 cross sections for suttering of hydrogen atoms by argon, krypton and xenon were measured PS a function of velocity in the range from 1.8 to 6.2 km/set. An analysis in terms of Lennsrd-Jbnes (12.6) and (8,6) model potentials leads to estimates of the interatomic forces.
