Plasma Diagnostics for Planetary Nebulae and H II Regions Using the N II and O II Optical Recombination Lines

We carry out plasma diagnostic analyses for 123 planetary nebulae (PNe) and 42 H II regions using the N II and O II optical recombination lines (ORLs). New effective recombination coefficients for the N II and O II optical recombination spectra are used. These data were calculated under the intermed...
