Random-interaction study on linear systematics of $I^{\pi }=11\mathrm{/}{2}^{-}$ electromagnetic moments in Cd isotope chain

In the random-interaction ensembles, electromagnetic moments of Cd $I^{\pi }=11\mathrm{/}{2}^{-}$ isomers predominately present linear systematics as changing the neutron number, which has been reported in realistic nuclear system. Quadrupole-like and $\delta$-like $pn$ interaction are responsible for such linear systematics of quadrupole and magnetic moments, respectively.
