Abstract
A variety of results have been proposed for the time taken by a tunneling particle for barrier traversal. We confirm one of the existing results by considering tunneling through a time-modulated barrier. At low modulation frequency the traversing particle sees an effectively static barrier. At high frequencies the particle tunnels through the time-averaged potential, but can do it inelastically, losing or gaining modulation quanta. The transition between the two regimes yields the traversal time. Estimates of this time are given for field-emission experiments, Zener tunneling and the tunneling of a Josephson junction circuit out of the superconducting state.
