Low-Energy Scattering Properties of Ground-State and Excited-State Positronium Collisions
Michael D. Higgins, Kevin M. Daily, Chris H. Greene
Low-energy elastic and inelastic scattering in the Ps(1)-Ps(2) channel is treated in a four-body hyperspherical coordinate calculation. Adiabatic potentials are calculated fo…
