In this work, we systematically investigate single-electron capture process in the collision between N
6+(1s) ions and H(1s) atoms in a wide energy range from 0.25 to 225 keV/u by using a two-electron semiclassical asymptotic-state close-coupling method. Spin-averaged and spin-resolved total cross sections, as well as
n-resolved and n\ell -resolved partial cross sections, are calculated and comprehensively compared with existing experimental measurements and theoretical predictions. The results show at low energies (<10 keV/u), energy dependence of the total cross section is weak, and it follows a monotonically decreasing trend at higher energies. The analysis of n\ell -resolved cross sections reveals the strong coupling effects between various channels at low energies, while at high energies the relative \ell distributions in each n\ell -resolved cross section approximately follow the statistical \ell distribution, for which the electrons are therefore mainly captured into subshells of the maximum \ell . The present study demonstrates the importance of a two-electron treatment taking into account electronic correlation and the use of extended basis sets in the close-coupling scheme. However, substantial discrepancies exist among theoretical approaches at low energies. It is clear that further experimental and theoretical efforts are required to draw definite conclusions. Our work provides a complete and consistent set of cross sections in a broad range of collision energies, which can be used for various plasma diagnosis and modeling.
