Coherent nuclear scattering of synchrotron radiation

Synchrotron radiation from modern electron storage rings can furnish brighter sources of Mössbauer radiation than radioactive sources if appropriate filtering can be devised. The object is to pass the power in the synchrotron radiation which lies in the spectral range within a few natural widths of the nuclear resonance, with as little diminuition as possible, and to reduce that passed outside this range to a fraction of the filtered radiation.
