Systematic calculations of electric dipole response with fully self-consistent Skyrme-RPA University of Aizu-JUSTIPEN-EFES Symposium on "Cutting-Edge Physics of Unstable Nuclei" Univ. of Aizu, November 10-13, 2010 INAKURA Tsunenori (RIKEN) NAKATSUKASA Takashi (RIKEN) YABANA Kazuhiro (Tsukuba)

Pygmy Dipole Resonance (PDR) Candidates for “soft dipole mode.” Strong impact on r-process. Nature of PDR is not well-known.  collective or single-particle excitation?  What is the condition for its emergence? P. Adrich et al., PRL 95,

PRC73, PRC76, (R) Precursive studies: PDR correlation with other quantities

Skyrme-RPA in 3D mesh T. Inakura et al., PRC80, Fully self-consistent Skyrme-RPA Including time-odd, residual LS and Coulomb. 3D mesh representation suitable to describe unstable nuclei. applicable for deformed nuclei. treat continuum in good approximation. No pairing correlation Technically… Finite Amplitude Method numerical estimation of residual interaction.. Response calculation at fixed complex energies. suitable for the paralleled supercomputer. 208 Pb

Systematic calc. of E1 mode SkM* interaction. 3D mesh. R box = 15 fm. No pairing. 39 spherical nuclei 153 prolate nuclei 54 oblate nuclei 51 triaxial nuclei nuclei

Extraction of PDR distribution

PDR distribution Deformed

PDR - diff. of Rrms, Sn, & N-Z asym. - Integration up to 10 MeV Lorentzian fitting

PRC73, PDR and diff. of Rrms

Integration up to 10 MeV Lorentzian fitting

A. Klimkiewicz et al., PRC76, (R) N-Z asymmetry

PDR: collective? 60 Ca SkM* R box = 25fm  = 0.5 MeV

Collective PDR SkM* interaction R box = 25 fm

PDR in 132 Sn E = i MeV R box = 25 fm SkM* interaction S n = 8.4 MeV Rrms = 4.9 fm

Summary PDR in light neutron-rich nuclei is mainly neutron emission mode from loosely-bound low-l orbit. Correlations with N-Z asymmetry and Sn are present. Strong correlations with Rn-Rp when the PDR grows up. PDR in light nuclei are single-particle excitations to continuum in RPA scheme. PDR in some heavy nuclei have collectivity.
