This passage discusses the near-threshold production of antihydrogen ion (H+) in positronium-antihydrogen collisions predicted by a rigorous four-body scattering calculation. It examines the convergence of cross sections for different reactions against partial waves, and finds large discrepancies in the production rates of H+ compared to more approximate calculations. The study also explores the multi-channel scattering solutions and their composition of functions to satisfy correct asymptotic boundary conditions.
Near-threshold production of antihydrogen ion (H+) in positronium-antihydrogen collisions is predicted by a rigorous four-body scattering calculation. The convergence of the cross sections for the rearrangement and for all competing reactions (elastic scattering, de/excitation and de/polarization of positronium) is carefully examined against partial waves. The multi-channel scattering solutions are composed of functions that diagonalize the four-body Hamiltonian, and scattering functions that satisfy the correct asymptotic boundary conditions. The production rates of H+ show large discrepancies compared to more approximate calculations.
