“…Experimental GDR data (aka cross section) have recently been available in the literature for several Dy isotopes providing some information for the region below 13 MeV in which only the first GDR peak was observed for 162,163 Dy isotopes [18]. Several theoretical works have calculated the GDR structures of the Dy isotopes using two different approaches [16,19]. The first theoretical attempt came from Oishi et al [16] in [156][157][158][159][160][161][162][163][164][165][166][167][168] Dy isotopes using Finite-amplitude method Quasiparticle Random Phase Approximation (QRPA) methodology within the Skyrme Energy Density Functional (EDF) framework.…”

“…However, the calculations are restricted only to gross features of the GDR and do not present any detailed information on the K splitting. In the second theoretical work, Peru et al [19] have delved into [156][157][158][159][160][161][162][163][164][165][166] Dy isotopes using QRPA with Gogny interaction. They have investigated the strength function for E1 and M1 transition probabilities below 20 MeV.…”

The electric dipole response of even-even ^154–164Dy isotopes

The excitation of pygmy dipole resonance (PDR) and giant dipole resonance (GDR) in even-even 154-164Dy isotopes is examined through quasiparticle random-phase approximation (QRPA) with the effective interactions that restores the broken translational and Galilean invariances. In each isotope, an electric response emerges by showing ample distribution at energies below and above 10 MeV. We, therefore, study the transition cross sections and probabilities, photon strength functions, transition strengths, isospin character, and collectivity of the predicted E1 responses.

Reliable predictions of the static and dynamic properties of a nucleus require a fully microscopic description of both ground and excited states of this complicated many-body quantum system. Predictive calculations are key to understanding such systems and are important ingredients for simulating stellar environments and for enabling a variety of contemporary nuclear applications. Challenges that theory has to address include accounting for nuclear deformation and the ability to describe medium-mass and heavy nuclei. Here, we perform a study of nuclear states in an Hartree-Fock-Bogoliubov (HFB) and Quasiparticle Random Phase Approximation (QRPA) framework that utilizes an axially-symmetric deformed basis. We present some useful techniques for testing the consistency of such calculations and for interpreting the results.
