Recent theoretical and experimental development of Mössbauer effect with synchrotron radiation

The elements of a dedicated beam line are introduced. Computer simulations of the nuclear monochromator response to an incident broad band of radiation show the special features of the new source-speed up, dynamical beats, quantum beats and polarization mixing. Experiments with YIG and FeBO3 confirm the theoritical picture. It is shown that time differential measurements have the potential of greatly improving the accuracy of future experiments. New fields of investigations will be broadband spectroscopy in the μeV range and γ-optics
