Physicists at the TU Darmstadt and their collaboration partners have performed laser spectroscopy on cadmium isotopes to confirm an improved model of the atomic nucleus. It has been developed to ...

Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts.

Ever stop to contemplate the size of an atom or ion? Martin Rahm, Roald Hoffmann, and Neil W. Ashcroft have. For consistency’s sake, these Cornell University scientists have just completed a ...
