The consideration applies to the energy range of thermal and resonance neutrons.The work is supported by the Belarus fund for fundamental research, grant $Phi$06P-074High Energy Physics - PhenomenologySensitivity of the neutron crystal diffraction experiment to the neutron EDM and to the nuclear P-,T-violating forcestext
