Received 18 June 2007; published 17 January 2008Positronium Ps -He scattering presents one of the few opportunities for both theory and experiment totackle the fundamental interactions of Ps with ordinary matter. Below the dissociation energy of 6.8 eV,experimental and theoretical work has struggled to find agreement on the strength of this interaction asmeasured by the momentum-transfer cross section
