Synchrotron radiation studies of nuclear-resonant scattering in the presence of strong electronic charge scattering

Abstract

The delayed nuclear-resonant Bragg scattering of synchrotron radiation at a strong allowed charge scattering peak in α${\mathrm{-}}^{57}$ ${\mathrm{Fe}}_2$ ${\mathrm{O}}_3$ has been observed. The detailed time dependence has been measured and successfully interpreted theoretically. This result demonstrates that it is no longer necessary to extinguish crystallographically the normal charge scattering in synchrotron radiation studies of nuclear-resonant scattering.
