Polarization Measurements in Nuclear Resonance Fluorescence Experiments

Abstract

Systematic photon scattering experiments have been performed over the recent years at the Giessen Electron Linac and Stuttgart Dynamitron in order to investigate low lying dipole transitions in deformed nuclei. With the high resolution and sensitivity of these Nuclear Resonance Fluorescence (NRF) experiments detailed dipole strength distributions in numerous isotopes could be extracted. By using linearly polarized bremsstrahlung or by measuring the linear polarization of the scattered photons the parities of numerous J=1 states in 48Ti, 70,72Ge, the rare earth nuclei 142,150Nd, 162Dy and in 232Th could be determined in an unambiguous, model‐independent way.
