Abstract:
We present new calculations for N III ion for diagnostics of solar plasma. The atomic model comprising the first 15 energy levels is considered for evaluating the line emissivities as a function of electron density and temperature, taking account of various physical processes. EUV line ratios, hitherto unexplored for diagnostic study, from this ion are presented as a function of electron density at its temperature of peak ionic concentration and their diagnostic applications in the solar atmosphere are discussed.
