Question

What is the functional role of energy-loss analysis?​

Answer 1

Answer:

Energy-loss function, defined as a function of momentum transfer and energy loss characterizes inelastic scattering process. The dielectric function in energy-loss function reflects the response of a solid to an external electromagnetic perturbation.

Answer 2

Energy-loss function, defined as Im[-1/ ε(q,ω) ] as a function of momentum transfer ℏq and energy loss ℏω , characterizes inelastic scattering process. The dielectric function ε(q,ω) in energy-loss function reflects the response of a solid to an external electromagnetic perturbation.
