The authors considerd how the probability of resonance tunneling is changed when there is superimposed on the stationary potential a nonstationary perturbation, which may be greater than or of the order of the width of a level in the well. The influence of nonstationary perturbation of the potential on tunneling was investigated numerically for the model of a barrier of zero radius, in which it was shown that at certain frequencies there can be complete reflection from the barrier. The authors write down quasiclassical solutions of the Schrodinger equation with the considered potential. Matching rules are obtained in neighborhoods of turning points and an equation is derived for the transmission probability amplitude. Quantization rules in the well are presented and an expression for the probability of nonresonance tunneling is given.
