Yuri Ralchenko led one of the oldest teams at the National Institute for Standards and Technology. The fate of some ...

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 Atomic Spectroscopy Group provides standardized measurements used across wide swaths of science and industry. The Trump administration plans... Trump cuts threaten a measurement lab critical for ...

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 ...

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 ...

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 ...

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 ...

Anritsu Company is launching an internal atomic clock option for its MS2720T Spectrum Master handheld spectrum analyzer that allows users to acquire excellent frequency accuracy, including in ...

The Trump administration is planning to close a small, obscure laboratory whose work undergirds everything from microchip manufacturing to nuclear fusion. The Atomic Spectroscopy Group at the National ...
