摘      要：In deep-inelastic collisions of 8 MeV/nucleon 70Zn projectiles with 198Pt, we have found an 8+ isomer with T1/2=23(1)ns at 4208 keV in 68Ni; the νg9/2 E2 effective charge was determined to be 1.5(1)e. In 69Cu, a 19/2− isomer with T1/2=22(1)ns at 3691 keV was identified and its decay data were calculated quite accurately by a parameter-free shell model calculation using empirical input parameters. Proton 2p- 1h excitation, fed by another T1/2=39(6)ns isomer at 3827 keV, induces large collectivity in 69Cu.
