Suppose a photon with wavevector k is being elastically scattered from, say, an atom into a state with different wavevector q, does it make sense to ponder the (average) duration of such an...

Louis, fascinating results, it appears. What is the profile of your light beam? How much of the area between the masses does it cover? Does it matter? Can you report on dependencies on laser...
