Photon Mass and New Experimental Results on Longitudinal Displacements of Laser Beams near Total Reflection
Abstract
Recent observations by Imbert to test predictions and observations of Goos and Hänchen by reflecting a laser beam near the total reflection angle contradicts classical and quantum predictions for the longitudinal displacements of linearly polarized incident plane waves. They can be simply interpreted as a Stern-Gehrlach type of measurement of the photon spin, provided the photon has a nonzero rest mass.
