In deep-inelastic collisions of 8 MeV/nucleon 70Zn projectiles with 198Pt, we have found an 8(+) isomer with T(1/2) = 23(1) ns at 4208 keV in 68Ni; the nug(9/2) E2 effective charge was determined to be 1. 5(1)e. In 69Cu, a 19/2(-) isomer with T(1/2) = 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 T(1/2) = 39(6) ns isomer at 3827 keV, induces large collectivity in 69Cu.
