Evaluation of the … WebElastic Scattering. Elastic scattering is a process where an incident electron is scattered by an atomic nucleus. Due to the great mass difference between an electron and a nucleus, the energy exchange between the incident electron and the nucleus is small and usually not measurable in EELS. This process contributes to the zero loss peak of EELS.
