We report on the observation of nuclear resonant forward scattering of synchrotron radiation from nuclei. A temperature stabilized α- crystal Bragg backscattering high-resolution monochromator with a relative energy resolution of was introduced. As first spectroscopic applications the hyperfine parameters in , USb and DySb were determined. The energy of the nuclear transition in was measured to be , 40 times more precisely than reported before. The results open the field of nuclear resonance spectroscopy on antimony compounds taking advantage of the outstanding features of 3rd-generation synchrotron sources. Nuclear resonance scattering on Sb compounds at these sources allows element-specific dynamical studies on thermoelectric materials as well as studies on magnetism in micro- and nanometer dimensional systems like spintronic devices.
