    • Neutron-deuteron analyzing power data at 19.0 MeV 

      Weisel, GJ; Tornow, W; Crowe, BJ; Crowell, AS; Esterline, JH; Howell, CR; Kelley, JH; ... (11 authors) (Physical Review C - Nuclear Physics, 2010-02-23)
      Measurements of neutron-deuteron (n-d) analyzing power Ay(θ) at En=19.0 MeV are reported at 16 angles from θc.m.=46.7 to 152.0°. The objective of the experiment is to better characterize the discrepancies between n-d data ...

    • 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 ...

    • Spectral structure of the pygmy dipole resonance. 

      Tonchev, AP; Hammond, SL; Kelley, JH; Kwan, E; Lenske, H; Rusev, G; Tornow, W; ... (8 authors) (Phys Rev Lett, 2010-02-19)
      High-sensitivity studies of E1 and M1 transitions observed in the reaction 138Ba(gamma,gamma{'}) at energies below the one-neutron separation energy have been performed using the nearly monoenergetic and 100% linearly polarized ...
