Description	Two high-resolution neutron diffractomers dedicated to strain/stress investigations in polycrystalline materials are routinely operated at the medium-power reactor LVR-15 in Řežand are also opened for external users. By exploiting Braggdiffraction optics, good luminosity of the diffractometers and a sufficiently high-resolution (FWHM(.delta.d/d) of the instrumental profile can be about 2x10.sub.-3 at d.sup.hkl=0.2nm) permit investigations of both the macro- and microstrainsin the sample gauge volume of several cubic millimetres. For scanning the position and profile and diffraction peaks, both diffractometers use the method of the Bragg diffraction angle analysis. However, a novel complementary modification of the method of energy-dispersive neutron-transmission diffraction for scanning Bragg diffraction edges can easilybe implemented on one of the diffractometers. Both methods permit us to determine lattice spacing changes .delta.d/d with the sensitivity down to 10.sub.-5 for small sample volumes and Two high-resolution neutron diffractomers dedicated to strain/stress investigations in polycrystalline materials are routinely operated at the medium-power reactor LVR-15 in Řežand are also opened for external users.
