Fine-structure population ratios for the 3P ground state of N II.
Abstract
R-matrix calculations of electron impact excitation rates for the 2s22p2 3PJ - 2s22p2 3PJ, fine-structure transitions in N II are used to derive the electron density (ne) and temperature (Te) sensitive population ratios f1 = n(3P1)/n(3P) and f2 = n(3P2)/n(3P) for a range of ne and Te appropriate to H II regions.
