Abstract
Theoretical calculations for magnetic moments of T=0 collective states in N=Z nuclei are compared with recent experimental results. The Jpi =2+ and 3- states considered all have 0.49<gtheor<0.51 if the wavefunctions have pure T=0 isospin. Isospin mixing increases the calculated 16O 3-g factor by 9%, consistent with experiment, but has a much smaller effect on the 2+ states. A reported negative experimental g factor for the 4+ state in 20Ne is in complete disagreement with theory.
