Parity assignments in 172,174Yb using polarized photons and the K quantum number in rare earth nuclei
Abstract
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 scattering (γ →, γ′) experiments. The
measured parities are compared with previous assignments based on the K quantum number
that had been assigned in nuclear resonance fluorescence (NRF) experiments by using
the Alaga rules. A systematic survey of the relation between γ-decay branching ratios
and parity quantum numbers is given for the rare earth nuclei. © 2005 The American

Professor Emeritus of Physics
Dr. Weller's research program at TUNL has been concentrated on using radiative capture
reactions induced by polarized beams of protons and deuterons to study nuclear systems.
These measurements have permitted him to observe the "D-state" in the 4He nucleus,
which arises from the two body tensor force. This result changes the rate of the d+d
fusion reaction by almost a factor of 50 at very low energies. This is of great interest
in nuclear astrophysics. In the past year, he has focused on studi
Ying Wu
Professor of Physics
Prof. Wu is interested in nonlinear dynamics of charged particle beams, coherent radiation
sources, and the development of novel accelerators and light sources. One of his research
focuses is to study the charged particle nonlinear dynamics using the modern techniques
such as Lie Algebra, Differential Algebra, and Frequency Analysis. This direction
of research will significantly further the understanding of the nonlinear phenomena
in light source storage rings and collider rings, improve their p
