On the Line Intensity Ratios E(Hα)/ E(D3) and E(Hβ)/ E(D3) in Prominences
Abstract
The intensity ratios E(Hα)/E(D3) and E(Hβ)/E(D3) in prominences depend on the total optical thickness in Hα of the layer. The emission of the He D3 line appears relatively enhanced in thin layers and in outer parts of the prominences.
