  The consideration is presented of possible neutron experiments to search for
new short-range spin-dependent forces. The spin-dependent nucleon-nucleon
interaction between neutron and nuclei may cause different effects: phase shift
of a neutron wave in neutron interferometers of different kind, in particular
of the Lloyd mirror configuration, neutron spin rotation in the pseudo-magnetic
field, and transverse deflection of polarized neutron beam by a slab of
substance. Estimates of sensitivity of these experiments are performed.
