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 (10[1])this phenomenon. According to the optical theorem, the imaginary part of an “amplitude” measuring the probability (-5[1])of this (10[1])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 (-5[1])is explained by (10[1])Lord (10[1])Rayleigh’s (10[2])form of this (10[2])phenomenon. (10[1])For 10 points, (10[1])particles strike each other and deflect in a form of what process named for Arthur Compton? (10[1])■END■
