Advanced Scattering Techniques

Abstract

Nuclear resonant scattering of synchrotron radiation can be used to extend the energy resolution and the time resolution of x-ray scattering techniques into regimes that have not been accessible so far. The essential idea is to manipulate the resonantly scattered photon fields by controlled motion of the nuclei during the scattering process. This has led to the development of x-ray monochromators with μeV resolution and the invention of the nuclear lighthouse effect that has the potential to achieve time resolutions in the ps range. These developments promise new spectroscopic techniques (elastic and inelastic) in the x-ray regime.
