shell model

[′shel ‚mäd·əl]
(nuclear physics)
A model of the nucleus in which the shell structure is either postulated or is a consequence of other postulates; especially the model in which the nucleons act as independent particles filling a preassigned set of energy levels as permitted by the quantum numbers and Pauli principle.

Based on presentations at the 15th National Conference on Nuclear Structure in China (NSC2014), held in October 2014 in Guilin, China, the 45 papers in this volume (contributed by an international group of physicists) address topics related to nuclear spectroscopy of high-spin states, nuclear mass and half-life, nuclear astrophysics, super-heavy nuclei, unstable nuclei, mean field theory, neutron star and symmetry energy, nuclear matter, nuclear shell model, and other topics related to nuclear structure.
In the nuclear shell model, successive levels alternate in parity, and so parity eigenstates are linear combinations of either even (|nh[omega]>, n even) or odd (|nh[omega]>, n odd) shell states.
