Terasaki, J.; Engel, J.

We describe a new implementation of the quasiparticle random-phase approximation (QRPA) in axially symmetric deformed nuclei with Skyrme and volume-pairing energy-density functionals. After using a variety of tests to demonstrate the accuracy of the code in Mg24,26 and O16, we report the first fully self-consistent application of the Skyrme QRPA to a heavy deformed nucleus, calculating strength distributions for several Kπ in Yb172. We present energy-weighted sums, properties of γ-vibrational and low-energy Kπ=0+ states, and the complete isovector E1 strength function. The QRPA calculation reproduces the properties of the low-lying 2+ states as well or better than it typically does in spherical nuclei.
