BARRIER TRAVERSAL TIMES USING A PHENOMENOLOGICAL TRACK FORMATION MODEL

摘要

A phenomenological model for a measurement of ''barrier traversal times'' for particles is proposed. Two idealized detectors for passage and arrival provide entrance and exit times for the barrier traversal. The averaged traversal time is computed over the ensemble of particles detected twice, before and after the barrier. The ''Hartman effect'' can still be found when passage detectors that conserve the momentum distribution of the incident packet are used. (C) 1997 Elsevier Science B.V. [References: 29]
