The g -factor of the 8 + isomer of 142 Eu

Theg-factor of the 8+ isomer of142Eu with mean lifeτ=9 ns, has been measured by the time-differential perturbedγ ray angular distribution (TDPAD) method. The 8+ isomer was populated with the reaction114Cd(32S,p3n)142Eu at 155 MeV. The obtained valueg(8+)=0.51(3) agrees with shell model calculations using effective single-particle moments taken from neighbouring nuclei. A main configurationπh11/2⊗(vh11/2)−1 has been confirmed for the 8+ isomer.
