6. H. Friedrich and J. Trost, Phys. Rev. Lett. 76, 4869 (1996): The approach in this paper is different from ours. They consider an intermediate wavelength range of a particle wavefunction (a wavelength between the short wavelength of the no-tunneling limit) and obtain a fairly accurate phase change due to reflection at the turning point.
