Calculations of positron scattering and annihilation from H-like ions

Year: 2025

Type: article

Abstract: The single-center convergent close-coupling method is utilized to calculate positron scattering from H-like ions from He+ to F8+. Results for the normalized annihilation rate ( Z eff ) and the electron-loss, elastic, and bound-state excitation cross sections are obtained for energies up to 10 keV. Excellent agreement is found between present and previous theoretical Z eff results for He+, Li2+, B4+, and F8+. As there is no previous work for the remaining cross sections the results for electron-loss are presented alongside previous theory and experiment for incident electrons. The differences between these cross sections give an insight to the impact of the projectile charge on scattering from highly-charged ions.
