Magnetic moment of the 19/2+ isomer in135Ce

Employing the time-integral PAC technique with an external magnetic field, the g-factor of the 19/2+ state at 2,125.6 keV in135Ce was determined to be g=−0.07(1). This value favours a predominant (h 11 2/−2 s 1 2/−1 ) neutron configuration for this level. Its meanlife has been redetermined with improved precision to be τ=11.8(5) ns.
