Abstract

First Nuclear Resonance Fluorescence (NRF) experiments were performed at the storage ring FEL-driven High Intensity Gamma Source (HIγS) at the DFELL. Azimuthal NRF intensity ratios were measured around the polarized HIγS beam. Electric character was deduced for 18 dipole excitations in ¹³⁸Ba [1]. The measurements demonstrate the superior performance of the HIγS facility in making such measurements. We report here on the performance of this set-up.
