Reply to the ‘Comment on “Perturbation theory of scattering for grazing-incidence fast-atom diffraction”’ by G. A. Bocan, H. Breiss, S. Szilasi, A. Momeni, E. M. S. Casagrande, E. A. Sánchez, M. S. Gravielle and H. Khemliche, Phys. Chem. Chem. Phys., 2023, 25, DOI: 10.1039/D3CP02486E

Abstract

Perturbation theory, in first order, fits experiment as well as DFT-based potentials suggesting modulation of the well-depth across the scattering channel contributes to observed changes in the rainbow angle.
