The magnetic moment of the 4+, 3.55 MeV level of 18O

Abstract The magnetic moment of the 4 + , 3.55 MeV level of 18 O has been determined to be | g | = 0.62 ± 0.10 in a perturbed angular correlation measurement on nuclei recoiling into gas and vacuum. Analysis of the recoil-into-gas data using the Abragam-Pound model agrees with analysis of the recoil-into-vacuum data using a model for the electronic ensemble described in a previous communication. The value of the g -factor shows the 4 + wave function to consist mainly of the d 5 2 2 configuration.
