Abstract
We discuss the time evolution in sub-barrier motion to investigate the unexpected effect discovered by Fletcher, namely the independence of the time delay on the barrier length for sufficiently long barriers. It is shown that the velocity of a wave packet under the barrier is exponentially decreasing from the beginning to the end of the barrier so the packet spends the main part of time penetrating the last part of the barrier.
