The g factor of the 4{sub 1}{sup +} state in {sup 66}Zn has been measured for the first time employing the technique of projectile Coulomb excitation in inverse kinematics combined with transient magnetic fields. The lifetime of this state, {tau}(4{sub 1}{sup +})=1.1(2) ps, which has been remeasured by the Doppler shift attenuation method, is twice as large as a previously determined value. Both the deduced B(E2;4{sub 1}{sup +}{yields}2{sub 1}{sup +})=133(24) e{sup 2} fm{sup 4} and the g factor of the 4{sub 1}{sup +} state, g(4{sub 1}{sup +})=+0.65(20), were interpreted, together with results for the 2{sub 1}{sup +} state, in the framework of shell-model calculations based on a {sup 56}Ni closed-shell core. The present results are also compared with those for neighboring {sup 64}Zn and {sup 68}Zn that were obtained in previous measurements by the same technique.
