Electron scattering mechanisms

WebApr 4, 2024 · The radiation frequency is limited to about 160 MeV. Through IC scattering, synchrotron photons can be scattered by the external electrons or by the electrons themselves that produce the synchrotron photons. Traditionally, synchrotron and IC mechanisms have been used to explain the emissions of high-energy objects above 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.

WebJun 8, 2024 · For an electron in Cu metal at 300 K, the scattering time τ is about 2 x 10 -14 s. From this we can calculate the mean free path as: (6.6.3) λ = v a v g τ ≈ v F τ = ( 1 × 10 6 m / s) ( 2 × 10 − 14) = 40 n m.
