WKB-approximation formulas are obtained for the Dirac equation for a strong external field (epsilon/sub 0/>2m/sub e/c/sup 2/, where epsilon/sub 0/ is the electron binding energy). These formulas are used to calculate the energy and width of the quasistationary states in the lower continuum and to determine the pre-exponential factor in the probability of the spontaneous positron creation. Other applications of the WKB method are briefly discussed.
