J/A+AS/103/273 IRON Project II. C-like ions (Lennon+ 1994) ================================================================================ Atomic Data from the IRON Project. II. Effective collision strengths for infrared transitions in carbon-like ions Lennon D.J., Burke V.M. =1994A&AS..103..273L ================================================================================ Keywords: Atomic data ADC_Keywords: Atomic physics Description (Abstract): We present new calculations of cross-sections for the electron impact excitation of carbon-like ions from N II to S XI, paying particular attention to the infrared transitions between the 2p^2^-3P J=0,1,2 ground state fine-structure levels. We also give rate coefficients, assuming a Maxwellian electron velocity distribution, in the form of effective collision strengths for these transitions up to an electron temperature of 10^5^K. We also give results for transitions involving the other 2p^2^ terms (^1^D and ^1^S) as well as the 2s2p^3^(^5^S) term. The present results are in excellent agreement with a number of similar calulations available in the literature but are more comprehensive in scope.
