solar spectra/ A9580 Astronomical observations A9660 Solar physicsObservations of a number of helium triplet ( λλ 10830, 4713, 4471, 3889, 4026) and hydrogen (H γ , δ , η , θ ) emission line intensities in six quiescent prominences are presented. The regions of prominence and ...
Fowler pointed out that a series of "parallelisms" that we gave of lines in the spectra of neon and hydrogen were probably coincidences, and could not be taken as evidence of identity. We are sorry that we did not make our meaning plainer, in our letter in NATURE for February 27, for...

We briefly summarize the present status of theoretical and experimental investigations aimed at describing the thermodynamic properties of hydrogen and helium at high density. We confront various theoretical models to presently available experiments and we consider the astrophysical implications for giant plane...
The emission spectra of hydrogen and helium differ because hydrogen is a one electron species and the interaction is only between the nucleus and the...Become a member and unlock all Study Answers Start today. Try it now ...
