Photon Mass and New Experimental Results on Longitudinal Displacements of Laser Beams near Total Reflection
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.
