The magnetic moment of the first excited state in138La

Abstract

The g-factor of the first excited state in the odd-odd nucleus 138La (E x =73 keV, U= 3 § T~/2=116ns) was measured by the time-differential perturbed angular distribution (TDPAD) method. The result, corrected for Knight shift and diamagnetic shielding, is g= +0.962 +0.016. This value can be fairly well reproduced using the additivity relation for magnetic moments, empirical values for the odd-proton and odd-neutron g-factors, and an experimentally deduced wave function for the 3 + state.
