Abstract
One-electron capture and target-ionization cross-sections in collisions of He+ ions with neutral atoms: He+ + A → He + A+ and He+ + A → He+ + A+ + e, A = H, He(1s2, 1s2s), Ne, Ar, Kr, Xe, are calculated and compared with available experimental data over the broad energy range E = 0.1 keV/u–10 MeV/u of He+ ions. The role of the metastable states of neutral helium atoms in such collisions, which are of importance in plasma physics applications, is briefly discussed. The recommended cross-section data for these processes are presented in a closed analytical form (nine-order polynomials) which can be used for a plasma modeling and diagnostics.
