Abstract

The g factors of the 2⁺₁ and 3^-₁ states in ⁹⁶Zr have been measured for the first time by Coulomb excitation of ⁹⁶Zr beams in inverse kinematics using transient magnetic fields. The resulting g factors are g(2⁺₁) = +0.03(7) and g(3^-₁) = +0.98(15). The lifetime of the 2⁺₁ state, τ = 0.82(10) ps, was redetermined via the Doppler Shift Attenuation Method. The 2⁺₁ → 0⁺₁ transition rate and the g-factor data are in fair agreement with shell-model calculations involving both proton and neutron excitations. The pronounced octupole strength of the 3^-₁ → 0⁺₁ transition is not seen in the g factor which exceeds significantly an expected Z/A value.
