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. (10[1])According to the optical theorem, (10[1])the imaginary part of an “amplitude” measuring the probability of this phenomenon equals k over 4 pi times the differential cross-section. Applying X-rays to a graphite target demonstrated one form of this phenomenon whose strength equals one minus cosine theta times a namesake wavelength of h over mc. The sky’s blue color (10[1])is explained by Lord Rayleigh’s form of this phenomenon. For 10 points, particles strike each other and deflect in a form of what process named for Arthur Compton? ■END■
