Experimental $g$ factor and $B(E2)$ value of the $4_1^+$ state in Coulomb-excited $^{66}$Zn compared to shell-model predictions

Abstract : The g factor of the 41+ state in 66Zn 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(41+)=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;41+-->21+)=133(24) e2 fm4 and the g factor of the 41+ state, g(41+)=+0.65(20), were interpreted, together with results for the 21+ state, in the framework of shell-model calculations based on a 56Ni closed-shell core. The present results are also compared with those for neighboring 64Zn and 68Zn that were obtained in previous measurements by the same technique.
