Abstract
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.
