 Abstract: We probe the $N=82$ nuclear shell closure by mass measurements of
neutron-rich cadmium isotopes with the ISOLTRAP spectrometer at ISOLDE-CERN.
The new mass of $^{132}$Cd offers the first value of the $N=82$, two-neutron
shell gap below $Z=50$ and confirms the phenomenon of mutually enhanced
magicity at $^{132}$Sn. Using the recently implemented phase-imaging
ion-cyclotron-resonance method, the ordering of the low-lying isomers in
$^{129}$Cd and their energies are determined. The new experimental findings are
used to test large-scale shell-model, mean-field and beyond-mean-field
calculations, as well as the ab initio valence-space in-medium similarity
renormalization group.
