Mössbauer Effect by Recoil Implantation Through Vacuum

摘要: The Mossbauer 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 radiation damage of the host medium by beam. Where comparison data are available copper, aluminum,and results at room temperature indicate that, within nuclear lifetime 10−7 sec, find a normal lattice site. A measurement with copper 5°K indicates similar result.Implantation germanium silicon showed two resonance lines. For Mg)2SiO4, is signifier alignment produced in Coulomb excitation process detecting gamma-r polarimeter. recoil pre ducing helium gas space traversed recoils.The application techniques used to other nuclei discussed. In particular, beam target requirements flight times considered.
