Atomic nuclei serve as prime laboratories for investigations of complex quantum phenomena, where minor nucleon rearrangements cause significant structural changes. Pb is the heaviest known neutron-deficient Pb isotope that can exhibit three distinct shapes: prolate, oblate, and spherical, with nearly degenerate excitation energies. Here we report on the combined results from three state-of-the-art measurements to directly observe these deformations in Pb.

- * The new mass data, with a precision around 1 keV/c², supports the robustness of the N=50 neutron shell closure and enables comparisons with advanced theoretical models for understanding nuclear properties.
- * The study also highlights the challenges faced by theoretical approaches, like ab initio calculations and density functional theory, in accurately predicting ground-state properties in the silver isotopic chain near the proton dripline.
