A combined rf-guided ion beam and photon emission spectroscopy method was developed to measure state-selective charge-transfer cross sections at energies of direct relevance for astrophysics and fusion-plasma diagnostics and modeling. As examples, the systems of He2+ and N5+ ions colliding on H2 were considered. Ion energy was varied down to energies as low as 5 eV/amu. Unexpected large differences with theory were observed implying that the present and future measurements are valuable as benchmarks for improving theoretical descriptions.
