Systematics of the dipole polarizability — •Isabelle Brandherm1, Peter von Neumann-Cosel1, Tobias Klaus1, Hiroaki Matsubara2, and Atsushi Tamii2 — 1Institut für Kernphysik, TU Darmstadt, Darmstadt, Germany — 2RCNP, Osaka, Japan
Inelastic proton scattering at extreme forward angles has been established as a tool to probe the electric dipole response in nuclei. From that the electric dipole polarizability can be obtained, which is a key observable to set constraints to the symmetry energy parameters of the equation of state and neutron skin thickness of nuclei. Over the last decade the electric dipole response in numerous nuclei has been measured at the Research Center for Nuclear Physics in Osaka, Japan. In this talk new result about the dipole response and dipole polarizability of 58Ni and 90Zr will be presented. Also the now available systematics of of the dipole polarizability will be discussed.
