In this study, octupole-deformed nuclei, such as that of ²²⁵Ra, are expected to amplify observable atomic electric dipole moments (EDMs) that arise from time-reversal and parity-violating interactions in the nuclear medium. In 2015 we reported the first “proof-of-principle” measurement of the ²²⁵Ra atomic EDM.
