Above potential barrier diffusion
A. E. Bernardini, S. De Leo, P. Rotelli
abstract: The stationary phase method is applied to diffusion by a potential barrier
for an incoming wave packet with energies greater then the barrier height. It
is observed that a direct application leads to paradoxical results. The correct
solution, confirmed by numerical calculations is the creation of multiple peaks
as a consequence of multiple reflections. Lessons concerning the use of the
stationary phase method are drawn.
