Abstract
We determine the semiclassical coherent-state propagator for a particl e going through one-dimensional evolution in a simple barrier potentia l. The described semiclassical method makes use of complex trajectorie s 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 heig ht.
