Recombination of Ne5+ was measured in a merged-beam type experiment at the heavy-ion storage ring CRYRING. In the collision energy range 0–110 eV resonances due to 2s22p → 2s2p2 (Δn = 0) and 2s22p → 2s23l (Δn = 1), core excitations were observed. The experimentally derived rate coefficients agree well with the calculations obtained using AUTOSTRUCTURE. At low energies, recombination is dominated by resonances belonging to the spinforbidden 2s2p2(4PJ)nl series. The energy-dependent rate coefficients were convoluted with a Maxwell–Boltzmann electron energy distribution to obtain plasma recombination rate coefficients. The data from the literature deviate from the measured results at low temperature.
