Abstract
Starting from the fact, that different rotations can lead to states with the same polarization but different phases the expressions of intensity and polarization of the forward diffracted beam after a Laue-case single crystal neutron interferometer are derived for the general case of phase shifts and spin rotations in both beam paths of the interferometer. A basic and instructive experiment where the polarization of the emerging beam is rotated by phase shift is discussed.
