On the over-barrier reflection in quantum mechanics with multiple degrees of freedom
arXiv:0704.0409 · doi:10.1103/PhysRevA.76.032114
Abstract
We present an analytic example of two dimensional quantum mechanical system, where the exponential suppression of the probability of over-barrier reflection changes non-monotonically with energy. The suppression is minimal at certain "optimal" energies where reflection occurs with exponentially larger probability than at other energies.
