Benjamin Mottelson was a US-born physicist who specialized in theoretical work on the structure of the atomic nucleus. During the 1950s, in close collaboration with his Danish colleague Aage Bohr, ...

Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team ...

The inclusion of the long-neglected tensor force into theoretical models revises our understanding of ‘magic numbers’ in the atomic nucleus The world of nuclear physics is a relatively ordered one.

Physicists Maria Goeppert Mayer and J. Hans D. Jensen develop a theory of the nucleus as composed of shells of protons and neutrons. It explains why nuclei with certain “magic numbers” of protons and ...

A lopsided atomic nucleus may help to refine nuclear theory. The stubby pear shape, described today in Nature, may also be pointing towards new tests of particle physics that could reveal why matter ...
