Main Question or Discussion Point
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 describe the exceptional behaviour of the radii of calcium isotopes. The results published in Physical Review Letters could be a step towards a global model of the nuclear structure.
