Semiquantum approach for fast atom diffraction: Solving the rainbow divergence

In this work we introduce a distorted-wave method, based on the initial value representation approach of the quantum evolution operator, in order to improve the description of rainbow effects given by the surface eikonal (SE) model for diffraction from crystal surfaces produced by grazing scattering...
