Abstract
We report on a high resolution sapphire backscattering monochromator installed
at the Dynamics beamline P01 of PETRA III. The device enables nuclear resonance
scattering experiments on M¨ossbauer isotopes with transition energies between 20 and
60 keV with sub-meV to meV resolution. In a first performance test with 119Sn nuclear resonance
at a X-ray energy of 23.88 keV an energy resolution of 1.34 meV was achieved. The
device extends the field of nuclear resonance scattering at the PETRA III synchrotron light
source to many further isotopes like 151Eu, 149Sm, 161Dy, 125Te and 121Sb.
