Paralleling the idea of electron shells in atomic physics, in 1949 scientists proposed the nuclear shell model: protons and neutrons sit in distinct nuclear shells, and additional energy input can ...

Magic numbers In 1949, Goeppert Mayer and Jensen developed the so-called shell model of the nucleus. Protons and neutrons occupy particular orbits, analogous to electrons, but they also have a ...

It has magic numbers of 82 protons and 126 neutrons. Examples of magic numbers and stable nuclei exist everywhere—but scientists couldn't explain them without the introduction of the shell model.

Maria Goeppert Mayer and J. Hans D. Jensen explained this phenomenon in the 1940s–1950s through the nuclear shell model, for which they were awarded the 1963 Nobel Prize in Physics.

One successful model describing this is the nuclear shell model, which treats nucleons as valence particles within a mean-field. Initially, this model was developed for nuclei near stability, where so ...

Unlike previous models that struggled to explain mercury’s asymmetric fission, this approach captures the unusual double-humped mass distribution seen in mercury-180, revealing how nuclear shell ...

High-energy protons emitted after hooking up with neutrons Protons and neutrons pair up, get speedy, even if other neutrons are watching.

This indicates that localized nuclear shell effects have a reduced influence on the nuclear charge radius in these heavy nuclei. The results were published in the scientific journal Nature.
