Abstrakt: Abstract: An in-beam Mssbauer spectrometer was set up at the VICKSI heavyion accelerator in Berlin. Coulomb excited Mssbauer nuclei can be implanted into arbitrary sample materials. Measuring temperatures may be varied from 5 K to 650 K. A typical scpectrum shown in this work can be measured within a few hours.57Fe was implanted into metals having large atomic volumes: Al, α-Zr, β-Sn. In these matrices the strongly undersized iron atom tends to occupy interstitial sites and may undergo dynamic processes.
