Self-consistent separable random-phase approximation for Skyrme forces: Giant resonances in axial nuclei

Self-consistent Skyrme quasiparticle random-phase approximation for use in axially symmetric nuclei of arbitrary mass

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 24,26Mg and 16O, we report the first fully self-consistent application of the Skyrme QRPA to a heavy deformed nucleus, calculating strength...

Giant dipole resonance in deformed nuclei: dependence on Skyrme forces

P.-G. Reinhard Institut für Theoretische Physik II, Universität Erlangen, D-91058, Erlangen, Germany; [email protected] (Dated: October 11, 2006) Abstract The giant dipole resonance (GDR) in deformed nuclei is analyzed using the self-consistent separable random-phase-approximation (SRPA) with Skyrme forces SkT6, SkM, SLy6 and SkI3. The deformed nuclei Nd and U are used as r...

Self-consistent calculations of the electric giant dipole resonances in light and heavy nuclei.

While bulk properties of stable nuclei are successfully reproduced by mean-field theories employing effective interactions, the dependence of the centroid energy of the electric giant dipole resonance on the nucleon number A is not. This problem is cured by considering many-particle correlations beyond mean-field theory, which we do within the quasiparticle time blocking approximation. The elec...
