    • Compton scattering from He 4 at the TUNL HIγ S facility 

      Li, X; Ahmed, MW; Banu, A; Bartram, C; Crowe, B; Downie, EJ; Emamian, M; ... (29 authors) (Physical Review C, 2020-03-01)
      © 2020 American Physical Society. Differential cross sections for elastic Compton scattering from He4 have been measured with high statistical precision at the High Intensity γ-ray Source at laboratory scattering angles ...

    • Electron beam energy spread measurements using optical klystron radiation 

      Jia, B; Li, J; Huang Scott, S; Schmidler, C; Wu, YK (Physical Review Special Topics - Accelerators and Beams, 2010-08-04)
      In accelerators, the electron beam longitudinal dynamics critically depend on the energy distribution of the beam. Noninvasive, highly accurate measurement of the energy spread of the electron beam in the storage ring remains ...

    • Parity assignments in 172,174Yb using polarized photons and the K quantum number in rare earth nuclei 

      Savran, D; Muller, S; Zilges, A; Babilon, M; Ahmed, MW; Kelley, JH; Tonchev, A; ... (13 authors) (Physical Review C - Nuclear Physics, 2005-03-01)
      The 100% polarized photon beam at the high intensity γ ray source (HIγS) at Duke University has been used to determine the parity of six dipole excitations between 2.9 and 3.6 MeV in the deformed nuclei 172,174Yb in photon ...
