J/A+AS/142/85Recombination coefficients for C II lines (Davey+, 2000)

Recombination coefficients for C II Davey A.R., Storey P.J., Kisielius R. <Astron. Astrophys. Suppl. Ser. 142, 85 (2000)> =2000A&AS..142...85DADC_Keywords: Atomic physics - Planetary nebulaeKeywords: atomic data - line: formation - H II regions - planetary nebulae: generalAbstract: Effective recombination coefficients are given for C II transitions between doublet states. The calculations are carried out in the temperature range 500-20000K and for an electron density of 10^{4}cm^{-3}. The effects of electron collisions on the excited states are included. The necessary bound-bound and bound-free radiative data are obtained from a new R-matrix calculation in which photoionization resonances are fully delineated, thereby accurately incorporating the effects of both radiative and dielectronic recombination. The R-matrix calculation includes all bound states with principal quantum number n≤15 and total orbital angular momentum L≤4. The effect of moving the resonance features to their experimentally determined positions is also investigated and found to be important at low temperatures.File Summary:
