Title:     32Ne and the "Island of Inversion": first in-beam gamma-ray spectroscopic study at the Radioactive Ion Beam Factory

Abstract: The Radioactive Ion Beam Factory (RIBF), a major upgrade of the existing heavy-ion accelerator facility at the RIKEN Nishina Center,
has been largely completed about 2 years ago.  Three new ring cyclotrons can boost the beam energies to 440 and 350 MeV/u for light and heavy ions, respectively.  While the intense, high-energy primary beams can be used directly for experiments, they will mostly be used to produce intense secondary radioactive ion beams by in-flight fragmentation or fission of heavy nuclei, including uranium, using the large acceptance, two-stage in-flight fragment separator BigRIPS.

I will give a short overview of the existing facilities and then focus on the first experimental campaign carried out with BigRIPS and the Zero Degree Spectrometer.  Particular focus will be given to the first in-beam gamma-ray spectroscopic study of the very neutron rich nucleus 32Ne and its implication for the "Island of Inversion".

Stimulants available 15 minutes before the talk.
