Title: Deformation Effects on the Pygmy Dipole Resonance
Speaker: Shuichiro Ebata
Date: Wednesday, Nov. 21st, 11:00-
Place: Room 203, RIBF building
Abstract:
We investigate the systematics of low-lying E1 mode
which is often called Pygmy dipole resonance(PDR).
We focus on the PDR of deformed nuclei, and
report the relation between the neutron skin-thickness and the PDR.
The deformed nuclei have the deviation in the PDR components(K=0 and K=1),
that can be seen in the results of very neutron-rich Sn isotopes
obtained by relativistic mean field theory[1].
They explain the deviation by the direction dependence of
the skin-thickness of deformed nuclei.
We pick up the deformed nuclei from our systematic study,
and discuss the relation between the skin-thickness and the deviation.
