This is the dominant mode of  photon-matter interaction at intermediate energies, and its inverse is sometimes called the Sunyaev-Zel'dovich effect and explains some of the anisotropy of the cosmic microwave background.
In the monoenergetic spectrum of a small particle detector, this interaction results in a namesake edge  and continuum whose shape may be predicted from the Klein-Nishina formula.

For ten points, name the  phenomenon of incoherent, elastic scattering of a photon by an electron for which the shift in photon wave-  length is equal to the namesake wavelength times the quantity one minus the cosine of the scattering angle.
