One form of this phenomenon can be eliminated by setting a magnetic sphere’s permeability equal to permittivity in the Kerker effect. The KdV equation’s soliton solutions can be found with an “inverse transform” named for this phenomenon. According to the optical theorem, the imaginary part of an “amplitude” measuring the probability of this phenomenon (10[1])equals k over 4 pi times the differential cross-section. Applying X-rays to a graphite target demonstrated (-5[1])one form of this phenomenon whose strength equals one minus cosine theta (-5[1])times a namesake wavelength of h over mc. The sky’s blue color (10[1])is explained (10[1])by Lord Rayleigh’s form (10[1])of this phenomenon. (10[1])For 10 points, particles (10[1])strike each other and deflect in a form of what process named for Arthur Compton? ■END■ (10[2])
