Web102 rijen · Strong Lines of Helium ( He ) Intensity. Vacuum. Wavelength (Å) Spectrum. Reference. WebA spectral line may be observed either as an emission lineor an absorption line. Which type of line is observed depends on the type of material and its temperature relative to another emission source. An absorption line is produced when photons from a hot, broad spectrum source pass through a cooler material.

WebThe recombination of hydrogen and helium at z~1000-7000 gives unavoidable distortions to the Cosmic Microwave Background (CMB) spectrum. We present a detailed calculation of the line intensities arising from the Ly-alpha (2p-1s) and two-photon (2s-1s) transitions for the recombination of hydrogen, as well as the corresponding lines from helium.

The major Fraunhofer lines, and the elements they are associated with, are shown in the following table: The Fraunhofer C, F, G', and h lines correspond to the alpha, beta, gamma and delta lines of the Balmer series of emission lines of the hydrogen atom.
