the magnet used in a stern gerlach experiment is .15 m long andhas a field gradient of dB/dz = 9T/m over its full length. If abeam of sodium atoms of speed 600 m/s passes through this magnetand then strikes a photographic plate at a distance of .80 m beyondthe magnet, what will be the separation between the two impactzones on the film? sodium has a total angular momentum quantumnumber J=1/2, contributed by the spin of the single electron in the3s subshell.
