Electromagnetic excitation of nickel nuclei at LAND/R3B — •Dominic Rossi — Institut für Kernchemie, Johannes Gutenberg-Universität Mainz, D-55128 Mainz, Germany
The dipole response of stable and unstable nickel isotopes has been investigated at GSI in Darmstadt. Relativistic secondary beams of 57−72Ni, with energies of approximately 500 MeV/u, have been produced in the projectile FRagment Separator (FRS) and subsequently excited by heavy-ion-induced Coulomb excitation at the LAND/R3B setup. Due to the possibility to perform kinematically complete measurements with this setup, the excitation energy distributions can be determined by reconstructing the invariant mass. Measurements with Pb and C targets allow extraction of pure electromagnetic excitation data, enabling the access to the dipole strength distribution in the continuum. Cross sections for selected isotopes will be presented.
