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 Rμν2-sector mass. © 2001 The American Physical Society.engArtigo10.1103/PhysRevD.64.0677012-s2.0-85038298653
