It is known that the measured and calculated g-factors of states in even-even nuclei have values g ≅ 0.5. Both the collective model and the LS limit of the shell model (with , ) can explain this. Here we note that the isoscalar g-factors of low-lying 1+, 3+, and 5+ states in medium-mass odd-odd nuclei have also been measured to have values close to 0.5. An up-to-date compilation of the experimental values is presented. Also included are the results of large-scale shell model calculations which agree very well with the experimental data. We show that the isoscalar g-factors in nuclei also approach 0.5 in the large-l limit for a single-j shell model.
