Four neutron Schroedinger wave interference experiments are described: (1) null Fizeau effect for thermal neutrons in thermal matter; (2) precision measurements of the energy dependent scattering length of U-235; (3) gravitationally induced quantum interference; and (4) investigation of incident beam coherence questions in dynamical diffraction experiments. In the Fizeau effect experiment it was verified that a neutron de Broglie wave is not affected by the state of motion of matter within fixed boundaries through which the neutron is propagating. Upper limits for the energy dependence of the neutron optical potential and the wavelength dependence of s-wave neutron scattering lengths were deduced. Using the neutron interferometric technique the energy dependent bound coherent scattering lengths of U-235 were directly measured in the energy range of 30 to 92 meV with an error of 0.3%. In the gravity induced quantum interference experiments (COW), the results showed that the observed loss of contrast of the interference pattern is caused in part by the bending of the perfect crystal neutron interferometer. Lastly, mathematical and numerical calculation techniques are presented to investigate the effect of wavefront modulation and transverse coherence of an incident neutron beam in dynamical diffraction experiments. Experimental and theoretical pendelloesung interference patterns in perfect silicon crystal were obtained and compared.
