Abstract: For characterizing the spectrum of Dirac radial equation we introduce the notion of the quantum defect $\delta_k$, which generalizes the corresponding notion for Schrödinger radial equation. The existence of $\delta_k$ is proved and the formulas for calculating $\delta_k$ are received for a broad class of the potentials.
