Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner structure to improve calculations of a phenomenon in atomic physics known as the ...

Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the ...

The hyperfine structure of atomic spectra arises from interactions between the electromagnetic moments of the atomic nucleus and the surrounding electrons. These interactions, dominated by the ...
