The g factors of the short-lived 2{sub 1}{sup +},4{sub 1}{sup +}, and 3{sub 1}{sup -} states in {sup 64}Zn and the 2{sub 1}{sup +},4{sub 1}{sup +},2{sub 2}{sup +}, and 3{sub 1}{sup -} states in {sup 68}Zn have been measured using the combined technique of projectile Coulomb excitation in inverse kinematics and transient magnetic fields. In addition, B(E2)'s have been deduced from remeasured lifetimes of several excited states employing the Doppler-shift-attenuation method. Whereas the present data for the 2{sub 1}{sup +} states agree very well with our previous results, the g factors of the other states have been determined for the first time. All experimental data were compared with results from large-scale shell model calculations based on proton and neutron configurations in the fp and fpg model spaces with {sup 40}Ca and {sup 56}Ni as inert cores, respectively.
