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 4.9to 8.1 MeV. The extracted B(E1) ↑ and B(M1) ↑ values for the total electric and magnetic dipole strength below the neutron separation energy are 0.9 ± 0.2e2 fm2 and 8.3 ± 2.0μ2N , respectively. These measurements are found to be in very good agreement with the predictions from an energy-density functional (EDF) plus quasiparticle phonon model (QPM). Such a detailed theoretical analysis allows to separate the pygmy dipole resonance from both the tail of the giant dipole resonance and multi-phonon excitations. Combined with earlier photonuclear experiments above the neutron separation energy, one extracts a value for the electric dipole polarizability of 206Pb of αD = 122 ± 10 mb/MeV. When compared to predictions from both the EDF+QPM aand a corresponding range for the slope of the symmetry energy of L = 48–60 MeV. This newly obtained information is also used to estimate the Maxwellian-averaged radiative cross section 205Pb(n, γ )206Pb at 30 keV to be σ = 130 ± 25 mb. The astrophysical impact of this measurement—on both the s-process in stellar nucleosynthesis and on the equation of state of neutron-rich matter—is discussed.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.physletb.2017.07.062","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tonchev, A.P."}],"nameIdentifiers":[{"nameIdentifier":"489254","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsoneva, T."}],"nameIdentifiers":[{"nameIdentifier":"489255","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bhatia, C."}],"nameIdentifiers":[{"nameIdentifier":"489256","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arnold, C.W."}],"nameIdentifiers":[{"nameIdentifier":"489257","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Goriely, S."}],"nameIdentifiers":[{"nameIdentifier":"489258","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hammond, S.L."}],"nameIdentifiers":[{"nameIdentifier":"489259","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kelley, J.H."}],"nameIdentifiers":[{"nameIdentifier":"489260","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kwan, E."}],"nameIdentifiers":[{"nameIdentifier":"489261","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Lenske, H."}],"nameIdentifiers":[{"nameIdentifier":"489262","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Piekarewicz, J."}],"nameIdentifiers":[{"nameIdentifier":"489263","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Raut, R."}],"nameIdentifiers":[{"nameIdentifier":"489264","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rusev, G."}],"nameIdentifiers":[{"nameIdentifier":"489265","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"静間, 俊行"}],"nameIdentifiers":[{"nameIdentifier":"489266","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tornow, W."}],"nameIdentifiers":[{"nameIdentifier":"489267","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"静間 俊行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"489268","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Pygmy and core polarization dipole modes in Pb-206: Connecting nuclear structure to stellar nucleosynthesis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pygmy and core polarization dipole modes in Pb-206: Connecting nuclear structure to stellar nucleosynthesis"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-27"},"publish_date":"2018-03-27","publish_status":"0","recid":"48643","relation_version_is_last":true,"title":["Pygmy and core polarization dipole modes in Pb-206: Connecting nuclear structure to stellar nucleosynthesis"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:25:53.268424+00:00"}
