Electric dipole polarizability of low-lying excited states in atomic nuclei
José Nicolás Orce, Cebo Ngwetsheni
Novel equations for the electric dipole polarizability of low-lying excited states in atomic nuclei -- and the related moment of the total photo-absorption cross…

Global trends of the electric dipole polarizability from shell-model calculations
José Nicolás Orce, Cebo Ngwetsheni, B. Alex Brown
Shell-model calculations of the electric dipole (E1) polarizability have been performed for the ground state of selected p- and sd-shell nuclei, substantially advancing previous kn…

A new spectroscopic probe to search for magic numbers at high-excitation energies
Cebo Ngwetsheni, Nico Orce
Empirical drops in ground-state nuclear polarizabilities indicate deviations from the effect of giant dipole resonances and may reveal the presence of shell effects in semi-magic n…
