Scattering a quantum particle on a potential step: Characteristic times
for its subprocesses -- transmission and reflection    [PDF]

N. L. Chuprikov

Asymptotic group transmission and reflection delay times for a particle scattering on a potential step are defined within the alternative model of this quantum scattering process, which allows tracing the dynamics of its subprocesses at all stages of scattering. Unlike its standard model ours predicts nonzero values of these time scales for this potential. Besides, we first introduce local dwell transmission and reflection times for the potential step, which are nonzero too.
