Precision spectroscopy of helium and other atomic systems is a vital area of research in modern physics, particularly in testing fundamental theories like quantum electrodynamics (QED).

as well as their potential applications in spectroscopy and cluster formation. One significant area of research involves the use of helium nanodroplets as a medium for studying molecular ions.

How do scientists know what spectral lines belong to which compound ... have to separate the signature of hydrogen from the ...

With Whitebark Energy’s bid for King Energy set to complete in March, exploration has fired up at King’s Alinya hydrocarbon-hydrogen-helium project in SA.

Lockyer shares the honour of discovering helium with Frenchman Pierre Janssen, who independently spotted the rogue spectral line in 1868. The pair coincidentally filed their paperwork on the same ...
