A crystal-di_raction experiment is discussed to test weak equivalence principle for neutrons. The idea of the experiment is based on essential magnification of any external force, acting on a neutron under di_raction at the Bragg angles close to the

We have measured the neutron electric dipole moment using spin rotation in a non-centrosymmetric crystal. Our result is d_n = (2.5 +- 6.5(stat) +- 5.5(syst)) 10^{-24} e cm. The dominating contribution to the systematic uncertainty is statistical in n

Diffraction enhancement of small effects affecting a neutron undergoing Laue diffraction at Bragg angles θB close to 90° is predicted and experimentally observed. The enhancement is due to the delay of the neutron inside the crystal during diffract
