W. Sturhahn et al., ELECTRON-EMISSION FROM FE-57 NUCLEI EXCITED WITH SYNCHROTRON-RADIATION, Physical review. B, Condensed matter, 53(1), 1996, pp. 171-175
Time-dependent electron emission from iron foils excited by synchrotro
n radiation at the 14.4-keV nuclear resonance of Fe-57 was observed. T
he measured time spectra are explained as the sum of three contributio
ns, the emission of conversion electrons with and without creating or
annihilating phonons during absorption and the emission of photoelectr
ons.
