Abstract

In stable and weakly bound neutron-rich nuclei, a resonance-like concentration of dipole states has been observed for excitation energies below the neutron-separation energy. This clustering of strong dipole states has been named the Pygmy Dipole Resonance (PDR) in contrast to the Giant Dipole Resonance (GDR) that dominates the E1 response. Understanding the PDR is presently of great interest in nuclear structure and nuclear astrophysics. High-sensitivity studies of E1 and M1 transitions in closed-shell nuclei using monoenergetic and 100% linearly-polarized photon beams are presented.

Pygmy and core polarization dipole modes in 206Pb: Connecting nuclear structure to stellar nucleosynthesis

Journal Article Tonchev, A. P. ; Tsoneva, N. ; Bhatia, C. ; ... - Physics Letters B

A high-resolution study of the electromagnetic response of ²⁰⁶Pb below the neutron separation energy is performed using a (γ→,γ') experiment at the HIγ→S facility. Nuclear resonance fluorescence with 100% linearly polarized photon beams is used to measure spins, parities, branching ratios, and decay widths of excited states in ²⁰⁶Pb from 4.9 to 8.1 MeV. The extracted ΣB(E1)↑ and ΣB(M1)↑ values for the total electric and magnetic dipole strength below the neutron separation energy are 0.9±0.2e²fm² and 8.3±2.0μmore »« less

Dipole response in Te 128 , 130 below the neutron threshold

Journal Article Isaak, J. ; Savran, D. ; Löher, B. ; ... - Physical Review. C

Numerous studies of the ground-state decay of the pygmy dipole resonance (PDR) have been carried out in the past. However, data on the decay of the PDR to low-lying excited states is still very scarce due to limitations of the sensitivity to weak branching transitions of experimental setups. Here, we present a detailed examination of the low-energy dipole response of ¹²⁸Te and ¹³⁰Te below their neutron separation thresholds of 8.8 and 8.5 MeV, respectively. Photonuclear reactions with the subsequent γ-ray spectroscopy of the decay channel with continuous-energy bremsstrahlung at varying endpoint energies and linearly polarized quasimonochromatic γ-ray beams with energies ranging from 2.7 to 8.9 MeV in steps of roughly 250 keV were used for probing the decay behavior of the low-energy dipole response in 128Te and 130Te. In addition, (γ,γ' γ") reactions were used to study the population of low-lying states of ¹²⁸Te. Spin-parity quantum numbers and reduced transition probabilities are determined for individual photo-excited states. The analysis of average decay properties for nuclear levels in narrow excitation-energy bins enable the extraction of photoabsorption cross sections, average branching ratios to themore »« less

Nuclear {gamma}-ray coincidence experiments in high-intensity photon beams

Journal Article Savran, D ; Loeher, B - AIP Conference Proceedings

High energy photons are an important experimental probe in nuclear structure physics and have been used in the past decades for the investigation of low-spin structures of atomic nuclei. A topic of particular interest in recent years in this field is the Pygmy Dipole Resonance, an electric dipole (E1) excitation mode located well below the E1 giant resonance. Even though the PDR has been investigated systematically using high energy photons its decay properties were not accessible up to now. New experiments using the method of {gamma}-{gamma} coincidences will allow to study this important quantity in detail.

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

Spectral Structure of the Pygmy Dipole Resonance

Journal Article Tonchev, A P ; Kwan, E ; Rusev, G ; ... - Physical Review Letters

High-sensitivity studies of E1 and M1 transitions observed in the reaction {sup 138}Ba(gamma-vector,gamma{sup '}) at energies below the one-neutron separation energy have been performed using the nearly monoenergetic and 100% linearly polarized photon beams of the HIgamma-vectorS facility. The electric dipole character of the so-called 'pygmy' dipole resonance was experimentally verified for excitations from 4.0 to 8.6 MeV. The fine structure of the M1'spin-flip' mode was observed for the first time in N=82 nuclei.
