RECOMBINATION RATE COEFFICIENTS OF BORON LIKE Ne

OpenAlex İngilizce

Recombination of Ne 5+ 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 2 s 2 2 p → 2 s 2 p 2 (Δ n = 0) and 2 s 2 2 p → 2 s 2 3 l (Δ n = 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 spin-forbidden 2 s 2 p 2 ( 4 P J ) 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.
