Earlier Mossbauer effect experiments of 57 Co diffused in Al show basically two different positions for the Co-atoms after irradiation of the sample with fast neutrons: substitutional Co and interstitial Co. In order to study the landing dynamics of

Mossbauer effect measurements were performed with sources of 133Xe implanted in polycrystalline iron at temperatures from 90 K to 480 K, using the 81 keV transition in 133Cs, in order to obtain information about the lattice sites of the implanted imp

The isomer shift values of 133Cs implanted in graphite, diamond, Te, Si, Ge, Cu, Zn, Mo, and W are found in a larger interval than those found in Cs and Cs-compounds. The extension to larger values are explained by the increase of electron densities

Pyrolytic graphite was implanted with133Xe at a dose of 5·1017 atoms/m2. The large anisotropy of the recoilless fraction of the133Cs daughter isotope suggested that the Xe is situated in between the carbon layers in the lattice. The cesium was found

Mossbauer effect measurements are reported with sources of 133Xe implanted in Mo, W and Ta by means of the Leuven Isotope Separator. Information about the direct environment of an implanted radioactive probe atom is obtained through the hyperfine int

New source activities for Mossbauer spectroscopy of the 40 keV transition in 129 Xe, the 37 keV transition of 121 Sb and the 9 keV transition in 83 Kr, were produced by cyclotron irradiations. Their merits and demerits relative to other source activi
