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