THE experimental study of atomic spectra has a long and distinguished history. Even the descriptive analysis of spectra in terms of series and term values the systematic botany of spectra has a ...

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

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 ...

Most terrestrial dark matter searches look for signatures of dark matter particles scattering off other particles. Researchers have now demonstrated a new search strategy that involves detecting ...

Shifting lines: has the Higgs affected this spectrum? (CC-SA BélaBéla) A new way of measuring how the Higgs boson couples to other fundamental particles has been proposed by physicists ...

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 ...

In 2002, a team of Russian and American scientists created the first ever atom of oganesson, which is the heaviest chemical element ever recorded to date. With an atomic number of 118, oganesson ...

The discovery of a small discrepancy in hydrogen’s atomic spectrum came at just the right time to push quantum theory forward. Measurements by Willis Lamb (shown here) and Robert Retherford became the ...

Bemnifosbuvir, a guanosine analogue, is in clinical trials against the Hepatitis C virus (HCV) and the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This compound undergoes a series of ...
