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 ...

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 ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

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 ...

A variety of models of carcinogenesis are reviewed, and in particular, the multistage model of Armitage and Doll and the two-mutation model of Moolgavkar, Venzon, and Knudson. Both the latter models, ...

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 medical dosimetry program of the Radiation Effects Research Foundation (RERF), formerly the Atomic Bomb Casualty Commission (ABCC), in Hiroshima and Nagasaki has been conducted since 1961.
