Does the order of elastic and inelastic scattering affect an image or is there a top bottom effect from inelastic scattering?

P Rez - Ultramicroscopy, 2024 - Elsevier
Especially for light elements inelastic scattering is more probable than the elastic scattering
that conveys the structural information. The question arises as to whether an image using …
