Abstract
Nuclei in the neutron-rich Ni region have been studied by $\gamma$-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.
