Description

The 68Ni nucleus has been identified among the products of deep-inelastic reactions of 64Ni projectiles bombarding 130Te and 208Pb targets. Three new states, including the high-lying 2+ (2033 keV) and the 0.86 ms 5- isomer, indicate a substantial subshell closure at neutron number N=40. The level structure and the observed very slow E3 transition speed are discussed within the shell model
