Inelastic scattering - Wikipedia

WebElectron Scattering When an electromagnetic wave is impingant on a free electron, it causes the electron to oscillate. The electron itself then emits a new electromagnetic wave, with the net eﬀect being that the original wave has been scattered through some angle.

The scattering angle due to inelastic scattering is, as a rule, small. In backscattering, an electron collides with the much heavier nucleus, which results in an elastic scattering event. The electron retains (most of) its energy, but changes its direction. The scattering angle may be large in this case. screen share galaxy s20
