Calculation of partial electron-transfer cross sections in 1–84-keV/amuHe2++H collisions

Results of large-scale close-coupling calculations are reported for the ${\mathrm{He}}^{2+}$+H collision system at energies of 1–84 keV/amu. The calculated transfer cross sections are seen to agree very well with most of the available experimental data at lower energies. At higher energies they constitute improved predictions of cross sections, which are needed for plasma diagnostics purposes. A previously proposed model which neglects intershell couplings in the final capture states is assessed with respect to the accuracy of its results for this collision system.
