Scientific paper

Recent R-matrix calculations of electron impact excitation rates in Fe VII are used to derive relative emission line strengths for a range of electron temperatures (Te of between 8000 and 120,000 K, inclusively) and densities (Ne of between 10 to the 4th/cu cm and 10 to the 10th/cu cm, inclusively) applicable to gaseous nebulae. The results are found to be significantly different from those of Nussbaumer and Storey (1982), especially at low temperatures.
