Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

WITH regard to Mr. Evans's communication to NATURE, September 4, p. 5, I should like to remark that while I have for some time recognised that the experimental evidence, on the whole, seems to be ...

And while simpler spectra like hydrogen and helium, which only have a few lines in their spectra, sound like "vaguely musical" chords, elements with more complex spectra consisting of thousands of ...

After a time this gas, when subjected to spectrum analysis, displays the characteristic yellow lines of helium. Ergo, one element, by a mere change of form, appears to have become another and ...

Discovered in the 1800s in the solar spectrum, helium has been an element that has eluded humans for centuries. Despite being listed as one of the most abundant elements in the universe, this ...

When the researchers examined the spectra of the 25 stars, they found several with a strong presence of helium and an absence of hydrogen (Class 1). Some possessed hydrogen as well (Class 2 and ...

THE spectra of helium and hydrogen have acquired considerable importance in view of the recent experimental researches of Prof. Fowler and the theoretical investigations of Dr. Bohr. Before the ...
