A discrete energy eigenvalue or spectroscopically resolved level of an atom or atomic ion, including degeneracy and fine or hyperfine structure as appropriate.
wp-physics-atomic_energy_leveliupac-energy-levelnist-asd-levelsEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Atoms possess discrete bound-state energy levels and continua, measured through spectroscopic transitions.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Energy levels are energies assigned to stationary or metastable atomic states.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Bound atomic energy levels are discrete spectral values of the atomic Hamiltonian, while ionization and scattering channels contribute continuous spectrum.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.
wp-operator_spectrumnist-asd-levelsEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Differences between levels contribute spectral line frequencies, subject to transition matrix elements and broadening.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Repeated inelastic thresholds directly supported discrete atomic excitation energies.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
