Rp. Stafford et al., ELECTRON-IMPACT EXCITATION OF N-III - FINE-STRUCTURE COLLISION STRENGTHS AND MAXWELLIAN-AVERAGED RATE COEFFICIENTS, Monthly Notices of the Royal Astronomical Society, 266(3), 1994, pp. 715-720
The R-matrix method is used to calculate collision strengths and Maxwe
llian-averaged rate coefficients for some fine-structure transitions i
n N III. Analytic fits are given for the rate coefficients for the ran
ge of temperatures 5000-200 000 K, so that they may be readily applied
to solar/late-type star and planetary nebula investigations. The pres
ent data have significant differences from earlier calculations.
