Extract

Detailed physical mechanisms responsible for excitation of spectral lines in gaseous nebulae have been known for 50 years, and reasonable estimates of nebular densities and temperatures were obtained in the late thirties and early forties. However quantitative chemical analyses have proven difficult partly because of uncertainties in atomic parameters (notably collision strengths) and partly because of complications posed by the nebulae themselves.
