Аннотация

We have studied the time delays of slow electrons scattered by a rectangular in spherical coordinates potential well as function of the well parameters. We have shown that electron interaction with the scattering center qualitatively depends on the presence of discrete levels in the well. While electron retention by the scattering center dominates for the potential well with no discrete levels, the appearance of a level leads to an opposite situation where the incident electron hardly enters the scatterer. Such a behavior of the time delay is universal since it is found not only for the first s-level but also for the subsequent arising s-, p-, and d-levels.
