In-beam gamma-ray spectroscopy of exotic nuclei at the RIBF

The presentation will address nuclear structure and shell evolution at
extreme isospin values, studied via in-beam gamma-ray spectroscopy at
intermediate energies following knockout reactions and inelastic
scattering. Besides an introduction of the setup, key results will be
presented that demonstrate the close cooperation between experiment
and nuclear structure and reaction theory.

Recent experimental results will be presented that demonstrate the
efficacy of the employed method. Particular emphasis will encompass nuclear 
structure around the potential new magic neuron numbers N=32,34, the 
assumed doubly magic nucleus 78Ni, as well as surprising phenomena around 
the doubly magic nucleus 132Sn.
