Time-dependent polarization in Mössbauer experiments with synchrotron radiation: Suppression of electronic scattering

National Synchrotron Light Source, Brookhaven National Laboratory, Upton, New York 11973

The resonant forward scattering of x-rays from ⁵⁷Fe nuclei is strongly polarization dependent. The broad-band excitation provided by synchrotron radiation (SR) results in an interesting time-dependent polarization mixing, which we will discuss. Further we demonstrate that by selecting only the component of the transmitted radiation which has a 90° rotated plane of polarization, the nonresonant (nonrotated) transmitted intensity can be substantially reduced. This new technique will allow full utilization of new powerful SR sources currently under construction.
