23. We note that by putting n=1 in Eq. (6) we obtain, as expected, the same expression of Eq. (2.6) as in Ref. 18 as well as Eq. (14a) in Ref. 20 apart from a misprint.

26. The group delay, or phase-time delay, as given by the derivative of the dephasing Δφ [as given by Eqs. (4) and (6)] with respect to the angular frequency ω, in both allowed and forbidden processes, is widely accepted (see Refs. 8, 11, 15, 18, 20), since the work by T.E. Hartman [J. Appl. Phys.33, 3427 (1962)] based on the stationary phase approximation. Some authors expressed their criticism of the validity of such a procedure, as such as F.E. Low and P.F. Mende, Ann. Phys. (N.Y.)210, 380 (1991). The phase-time model, however, appears to be thus far the most suitable to interpret the experimental results.
