Abstract
Relative ionic population and line intensity ratios have been calculated for the ten n=2 levels of Ne VII over a range of electron densities, 1012-1017 cm-3 and temperatures, 5*102-4*106K, suitable for comparison with laboratory experiments. Electron excitation rates have been calculated using the R-matrix method, with the effect of proton and electron collisions between the fine-structure triplet levels being considered. A calculation including the effects of cascading from the n=3 levels indicates that, although the processes are not important at high densities, the predicted ratios change by up to 40% at the lowest density considered. A brief comparison is also made with experimental results.
