The three-body boundary-corrected continuum intermediate state (BCIS-3B) method is employed to compute single-electron capture cross sections. These data are for collisions in which a target helium atom in its ground state is impacted by multiply charged nuclei (specifically ). Intermediate and high projectile energies are considered (20 keV/amu-3 MeV/amu). The obtained results are tabulated for total cross sections (state-selective as well as state-summed and ). Cross section corresponds to a fixed triple of the hydrogenlike quantum numbers In and the sums over and are carried out, respectively. For in the Oppenheimer scaling rule is adopted. The values of are set to 4 (for ), 5 (for ), 6 (for ) and 7 (for ). Exhaustive comparisons of the theoretical findings for with the corresponding experimental data are performed. It is determined that the BCIS-3B method is in excellent agreement with the available measurements. The present database for the examined capture processes is deemed to be of notable practical usefulness in versatile applications of particular relevance to plasma physics, astrophysics, fusion research and ion therapy in medicine.
