Dielectronic recombination rate coefficient to the excited to the excited states of Be-like ions

Energy levels, radiative transition probabilities and auto-ionization rates for Be-like Ne (Ne6+) including 1s22pnl (n = 2 - 9, l ≤ 9) and 1s23l'nl (n=3 - 6, l ≤ (n - 1)) states are calculated by using multi-configurational Hartree-Fock (Cowan code) method. Autoionizing levels above the 1s22s and 1s22p thresholds were considered and their contributions were computed. The dielectronic recombination rate coefficients from Li-like Ne (Ne7+) ions to Be-likeNe (Ne6+) ions for excited states of Ne6+ ions are calculated. The values for the excited states with higher principal quantum number n are extrapolated and the total dielectronic recombination rate coefficients are derived. (author)
