A beam of electrons with kinetic energy 50 eV strikes the surface of a NaCI crystal. The spacing between the planes of the crystal is 0.281 nm. At what angle to the surface do we see a maximum in the reflected electron beam? (You can assume the electrons are nonrelativistic, and therefore K - p2/2m.) The same beam of electrons impinges on a pair of slits. A first-order diffration maximum is seen at 30 degrees to the incoming electron direction....

1. Neutron Diffraction While not discovered until 1932, neutrons are neutral subatomic particles possessing magnetic moments. As a result, neutrons will diffract from the layers of a crystal lattice, due to their magnetic interactions with atomic electrons. A beam of 1.0 eV neutrons strikes a crystal whose lattice planes are separated by 0.025 nm. In convenient units, the neutron mass is Mn = 940 MeV/ca. Determine the angle 6 between the incident and scattered neutron beams, for which the first...
