Quantum Defect Theory

Quantum Defect Theory is a theoretical framework in atomic physics that generalizes the electronic energy levels of alkali atoms by modeling the deviation from hydrogenic behavior through an empirical quantum defect parameter that accounts for core penetration and polarization effects.
