Abstract

The Mössbauer effect was observed for Coulon d Fe57 recoils implanted through vacuum into various media [copper, aluminum, gold, iron, germanium, silicon, graphite, Fe2O3, and (Fe, Mg)2SiO4]. This method avoids heating and radiation damage of the host medium by the beam. Where comparison data are available for copper, gold, aluminum,and iron, the results at room temperature indicate that, within the nuclear lifetime of 10−7 sec, the recoils find a normal lattice site. A measurement with copper at 5°K indicates a similar result.Implantation into germanium and silicon showed two resonance lines. For graphite, Fe2O3, and (Fe, Mg)2SiO4, the Mössbauer effect is signifier alignment of the nuclear recoils produced in the Coulomb excitation process was observed by detecting the gamma-r a Mössbauer polarimeter. The recoil alignment was pre ducing helium gas into the space traversed by the recoils.The application of the techniques used for Fe57 to other Mössbauer nuclei is discussed. In particular, beam and target requirements and recoil flight times are considered.
