Abstract
Nuclei in the neutron-rich Ni region have been studied by
-ray spectroscopy. Gamma-rays emitted from isomers,
with
T1/2>1 ns, produced in heavy-ion deep-inelastic
collisions were measured with an isomer-scope. The nuclear
structure of the doubly magic
68Ni and its neighbor
69,71Cu is discussed on the basis of the shell
model. Future experiments for more neutron-rich Ni nuclei are
also viewed.
