Description
Our recently proposed generalized seniority scheme has been widely successful in explaining the reduced transition probabilities of high spin isomers and other excited states in semi-magic nuclei [1-5]. In the present paper, we use this formalism to obtain the g-factors of semi-magic nuclei, particularly for Sn and Pb isotopes. We find that the magnetic moment and the g-factor values do show a particle number independent behavior for a multi-j, mixed configuration states where generalized seniority is applicable, as expected by us [4]. The calculated results explain the experimental trends quite well. As a result, we further confirm that g-factors of all the states arising from a given mixed configuration having identical nucleons must be equal to the g-factor of a single nucleon in the same mixed configuration. This opens up a way to make predictions more easily.

| Summary | Our generalized seniority scheme has widely been accepted in explaining the transition probabilities for semi-magic isomeric states. We now extend our calculations to obtain g-factors in semi-magic nuclei, which explains the experimental trends quite well. We also find and confirm that the g-factors of all states arising from a given mixed configuration having identical nucleons must be equal to the g-factor of a single nucleon in the same mixed configuration. |
