Abstract
To characterize the Dirac radial equation spectrum, we introduce the n otion of a quantum defect delta(k), which is a generalization of this notion for the Schrodinger radial equation. The existence of delta(k) is proved and explicit formulas for calculating delta(k) are found for a broad class of potentials.
