Recombination coefficients for Ne II lines at nebular temperatures and densities

We calculate total recombination coefficients for Ne2+ + e(-) and effective recombination coefficients for the formation of selected lines of Ne-II. New photoionization data are calculated which accurately map the near threshold resonances and are used to derive recombination coefficients for principal quantum numbers, n less than or equal to 15, including radiative and dielectronic recombination. Cascading from higher states is included, allowing for the effects of finite electron density in a hydrogenic approximation. The effects of population in the excited states of the recombining ion are investigated.
