Abstract
Observations are reported on single-slit diffraction of monochromatic slow neutrons (wavelength 4.43 Å) upon passage through fine slits of width between 21 and 4.1 μ. Gadolinium-edged slits were used because of the high-absorption cross section for this material, and the angular broadening effects in the range up to 20″ of arc were studied on a high-resolution double-crystal spectrometer utilizing perfect crystals of silicon. The observed broadening agrees well with that calculated, and this supplies evidence on the width of the coherent wavefront of a neutron wave packet.Keywords
