Phys. Rev. Lett. 79, 3323–3326 (1997)Phase-Space Approach to the Tunnel Effect: A New Semiclassical Traversal TimeReceived 2 June 1997; published in the issue dated 3 November 1997 We determine the semiclassical coherent-state propagator for a particle going through one-dimensional evolution in a simple barrier potential. The described semiclassical method makes use of complex trajectories which, by its turn, enables the definition of (real) traversal times in the complexified phase space. We then discuss the behavior of this time for a wave packet whose average energy is below the barrier height. © 1997 The American Physical Society URL:
