|Title:||TUNNELING TIME PROBLEM - MORE ABOUT THE TIME ANALYSIS OF TUNNELING PROCESSES - RESPONSE|
|Abstract:||In our recent review article [Phys. Rep. 214, 339 (1992)] we put forth an analysis of the main theoretical definitions of the sub-barrier tunnelling and reflection times, and proposed new definitions for such durations which seem to be self-consistent within conventional quantum mechanics. Very recently, in this Journal [Solid State Commun. 85, 115 (1993)], a paper by C.R. Leavens appeared claiming our definitions to be 'seriously flawed', on the basis of some numerical calculations for the average transmission times. We have nothing to object to those Leavens' calculations; except that they, simply, do not refer to our approach. In fact, they are based on equations different from the formulae proposed by us; in other words, Leavens' conclusions are valid for theories different from ours. We show in this note how further calculations, based on our own equations, do confirm that our approach is physically acceptable. Further criticism about our analysis of the dwell-time approaches is herein answered and commented.|
