The energy-dependent contribution to the deflection of photons passing by the Sun is computed and subsequently the angle at which the visible spectrum would be spread over is plotted as a function of the R-mu nu(2)-sector mass.3engArtigo10.1103/PhysRevD.64.067701WOS:000170978200079Acesso restritoWOS000170978200079.pdf
