Abstract
It is shown that, for energies E0, the barrier height, the typical tunneling time is on the order of 10-15 s. The traversal time as a function of kinetic energy is locally symmetric near E=V0. The tunneling time depends on the shape of the wave packet. The tunneling time is linearly dependent on barrier thickness for a wave packet with finite width. These conclusions are compared with the results obtained from other methods for estimating tunneling times.
