摘要：

Extending the results obtained in previous papers, an asymptotic analysis is applied to the problem of the penetration of a square potential barrier; it is shown that also in the classically forbidden case a velocity can be attributed to the particle, analogous to the usual group velocity and determining the traversal time.
