Outline of Final Research Achievements

We have measured the two-type angular distributions of Fe-K X-ray emissions with different time windows from a single-crystalline hematite (alpha-Fe2O3) with enriched 57Fe irradiated by incident 14.4keV gamma-rays at BL09XU/SPring-8. Gamma-rays of 14.4 keV can excite 57Fe nuclei with a lifetime of 100 ns. We found that the time-delayed angular distribution component of Fe-K X-rays has a different pattern compared with angular distributional component of Fe-K from fluorescent X-ray holographic pattern with Kossel lines.
