Abstract

Two examples of recent work on the structure of low-energy electric dipole modes are presented. The first part discusses the systematics of the pygmy dipole resonance (PDR) in stable tin isotopes deduced from high-resolution ({gamma},{gamma}') experiments. These help to distinguish between microscopic QRPA calculations based on either a relativistic or a nonrelativistic mean-field description, predicting significantly different properties of the PDR. The second part presents attempts to unravel the structure of dipoles modes at energies below the giant dipole resonance (GDR) in {sup 208}Pb with a high-resolution measurement of the (p-vector,p-vector') reaction under 0 deg.

Pygmy and Giant Dipole Response Function in Neutron Rich Nuclei at Finite Temperature

Journal Article Sahin, Ersin; Bozkurt, Kutsal; Sirin, Mehmet - AIP Conference Proceedings

We investigate pygmy and giant dipole resonance (PDR-GDR) for the case of neutron rich soft nuclei {sup 68}Ni and heavy nuclei {sup 208}Pb using effective nucleon-nucleon Skyrme interactions SLy7 and KDEO at finite temperature. We use the mean-field theory (HF) and employ the random phase approximation (RPA) in a coordinate space. We then compare the PDR calculations for the different Skyrme interactions with their experimental results. We find that the PDR and GDR strength distribution depends sensitively on temperature, and especially for {sup 68}Ni the collective effects almost disappear at T = 4 MeV.

Splitting of the Pygmy Dipole Resonance

Journal Article Endres, J; Zilges, A; Butler, P; ... - AIP Conference Proceedings

In recent years investigations have been made to study the electric Pygmy Dipole Resonance (PDR) systematically, mainly in semi-magic nuclei. For this purpose the well understood high resolution ({gamma},{gamma}') photon scattering method is used. In complementary ({alpha},{alpha}'{gamma}) coincidence experiments at E{sub {alpha}} = 136 MeV a similar {gamma}-energy resolution and a high selectivity to E1 transitions can be obtained at the Big-Bite Spectrometer (BBS) at KVI, Groningen. In comparison to the ({gamma},{gamma}') method a structural splitting of the PDR is observed in the N = 82 nuclei {sup 138}Ba and {sup 140}Ce and in the Z = 50 nucleus {supmore »« less

Study of the Pygmy Dipole Resonance in {sup 124}Sn by means of the ({alpha},{alpha}'{gamma}) reaction

Journal Article Endres, J; Zilges, A; Pietralla, N; ... - AIP Conference Proceedings

In recent years {alpha}-{gamma} coincidence experiments at 136 MeV incident energy on {sup 48}Ca, {sup 140}Ce, {sup 138}Ba and {sup 124}Sn were performed at the KVI in Groningen to study the isospin character of electric dipole excitations below the particle threshold, frequently called Pygmy Dipole Resonance (PDR). An array of HPGe {gamma}-detectors has been used in coincidence with the Big-Bite Spectrometer (BBS) and a resolution of about 10 keV in the {gamma}-ray energy has been achieved. The results show that the excitation patterns of the PDR in the ({alpha},{alpha}') reaction seem to differ significantly from results obtained in Nuclear Resonancemore »« less

Nuclear symmetry energy and neutron skins derived from pygmy dipole resonances

Journal Article Klimkiewicz, A; Adrich, P; Paar, N; ... - Physical Review. C, Nuclear Physics

By exploiting Coulomb dissociation of high-energy radioactive beams of the neutron-rich nuclei {sup 129-132}Sn and {sup 133,134}Sb, their dipole-strength distributions have been measured. A sizable fraction of ''pygmy'' dipole strength, energetically located below the giant dipole resonance, is observed in all of these nuclei. A comparison with available pygmy resonance data in stable nuclei ({sup 208}Pb and N=82 isotones) indicates a trend of strength increasing with the proton-to-neutron asymmetry. On theoretical grounds, employing the RQRPA approach, a one-to-one correlation is found between the pygmy strength and parameters describing the density dependence of the nuclear symmetry energy, and in turn withmore »« less

Pygmy dipole resonances in the tin region

Journal Article Tsoneva, N; Lenske, H - Physical Review. C, Nuclear Physics

The evolution of the low-energy electromagnetic dipole response with the neutron excess is investigated along the Sn isotopic chain within an approach incorporating Hartree-Fock-Bogoljubov (HFB) and multiphonon quasiparticle-phonon model (QPM) theory. General aspects of the relationship of nuclear skins and dipole sum rules are discussed. Neutron and proton transition densities serve to identify the pygmy dipole resonance (PDR) as a generic mode of excitation. The PDR is distinct from the GDR by its own characteristic pattern given by a mixture of isoscalar and isovector components. Results for the {sup 100}Sn-{sup 132}Sn isotopes and the several N=82 isotones are presented. Inmore »« less
