    "abstract": "The stationary phase method is applied to diffusion by a potential barrier\nfor an incoming wave packet with energies greater then the barrier height. It\nis observed that a direct application leads to paradoxical results. The correct\nsolution, confirmed by numerical calculations is the creation of multiple peaks\nas a consequence of multiple reflections. Lessons concerning the use of the\nstationary phase method are drawn.",
