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.

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.
