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 ...

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 ...

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 ...

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 ...

PROF. L. VEGARD'S recent note 1 on the atomic lines in the auroral spectrum calls for some comments. While it is true that the presence of the Vegard-Kaplan bands in auroral spectra was first observed ...

Scientists have carried out ground-breaking experiments to investigate the atomic structure of astatine (atomic number 85), the rarest naturally occurring element on Earth. Through experiments ...
