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 ...

The ability to locate and count small numbers of impurity atoms could lead to advances in modern electronics and optical fiber communication networks. In research published today in Physical Review ...

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 ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

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 ...

Balloons filled with hydrogen and containing metal salts are ignited. When the balloon explodes, the characteristically colored flame for that metal is seen. This is best performed outside or in a ...

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 ...
