Inversion of dynamical electron diffraction data including absorption

A method to invert the dynamical diffraction of high‐energy electrons inside a crystal, which takes into account absorption, is discussed. It is shown that, working at fixed energy, the projected potentials associated with both the elastic and the absorptive scattering can be uniquely obtained from...

Zusammenfassung:A method to invert the dynamical diffraction of high‐energy electrons inside a crystal, which takes into account absorption, is discussed. It is shown that, working at fixed energy, the projected potentials associated with both the elastic and the absorptive scattering can be uniquely obtained from the scattering matrix. Inversion is possible for any principal orientation of the incident beam. Model examples are given.
