Abstract:

In random-interaction ensembles, the electric quadrupole moments (Q) and magnetic moments (μ) of the I π =11/2- isomers of the Cd isotopes predominantly exhibit a linear correlation with the neutron numbers, corresponding to the recently emphasized linear Q and μ systematics in realistic nuclear systems. Although the seniority scheme enhances such predominance (more essentially for μ), the configuration mixing due to quadrupole- like and d-force-like proton–neutron (pn) interactions is responsible for the linear Q and μ systematics, respectively, in realistic nuclear system, as well as randominteraction ensembles.
