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 ...

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 ...

THIS little book endeavours to give a comprehen- sive, but not too advanced, treatment of the theory of atomic spectra. The subject is presented so as to avoid the need for much mathematical knowledge ...

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 ...

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 ...
