Elastic scattering formula
WebThe electron form factors are normally calculated from X-ray form factors using the Mott–Bethe formula. [4] This formula takes into account both elastic electron-cloud scattering and elastic nuclear scattering. Neutron form factor [ edit] There are two distinct scattering interactions of neutrons by nuclei. WebElastic scattering can also take place by the formation of a compound nucleus, with the subsequent re-emergence of a particle of the same type as the incident particle (no other …

WebElastic and inelastic scattering [ edit] The term "elastic scattering" implies that the internal states of the scattering particles do not change, and hence they emerge unchanged from the scattering process.
