It is shown that a spin‐orbit interaction of neutrons with crystal nuclei leads to a new phenomenon: neutron spin precession in nonmagnetic unpolarized single crystals and spin dichroism. The spin of the diffracted neutrons with a wavelength of 0.15 nm is rotated by 1.2 rad after transmission of neutrons through a tungsten carbide crystal (WC) of thickness 1 cm, set in exact symmetric Laue diffraction position (211). The neutron spin is rotated in the diffraction plane.
