摘要：

The Ni68 nucleus has been identified among the products of deep-inelastic reactions of Ni64 projectiles bombarding Te130 and Pb208 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. © 1995 The American Physical Society.
