Implantation of Coulomb excited57Fe

In beam Mößbauer spectroscopy: 57Fe in semiconductors

“…The implanted nuclei emit immediately (with their lifetime of 140 ns) 14.4 keV 7-quanta which are analysed outside the scattering chamber. If a pulsed beam with a pulse separation larger than the nuclear lifetime is used, the spectra can be recorded as a function of time after implantation [4]. This makes it possible to attempt to study e.g.…”
