      abstract     = {A sapphire backscattering monochromator with
                      1.1 (1) meV bandwidth for hard X-rays (20-40 keV) is
                      reported. The optical quality of several sapphire crystals
                      has been studied and the best crystal was chosen to work as
                      the monochromator. The small energy bandwidth has been
                      obtained by decreasing the crystal volume impinged upon by
                      the beam and by choosing the crystal part with the best
                      quality. The monochromator was tested at the energies of the
                      nuclear resonances of (121)Sb at 37.13 keV, (125)Te at
                      35.49 keV, (119)Sn at 23.88 keV, (149)Sm at 22.50 keV
                      and (151)Eu at 21.54 keV. For each energy, specific
                      reflections with sapphire temperatures in the 150-300 K
                      region were chosen. Applications to nuclear inelastic
                      scattering with these isotopes are demonstrated.},
