Abstract

The g factor of the first 2⁺ ₁ state of radioactive ⁷⁶Kr ( T _1/2 = 14.8 h) has been measured using projectile Coulomb excitation in inverse kinematics combined with the transient magnetic-field technique. The ⁷⁶Kr beam was produced and accelerated in batch mode (re-cyclotron method) at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. The g factor g(⁷⁶Kr; 2⁺ ₁) = +0.37(11) was obtained.
