A bound or resonant system of interacting protons and neutrons with internal excitations and collective modes.

This is an authored directed relation from the source endpoint to the target endpoint.
Nuclei are many-nucleon quantum systems of protons and neutrons.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

This is an authored directed relation from the source endpoint to the target endpoint.
An atomic nucleus is a nuclear many-body system with specified proton and neutron content.
The target is a member or subtype of the broader source class.

The liquid-drop model coarse-grains the nucleus into bulk and surface energy terms.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

Mean-field theory replaces much of the many-body interaction by self-consistent fields.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

The shell model truncates to selected single-particle orbitals and an effective interaction.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.
