Direct Evidence for Octupole Deformation in ${}^{146}$Ba and the Origin of Large $E1$ Moment Variations in Reflection-Asymmetric Nuclei

Brian Bucher, Shaofei Zhu, Ching-Yen Wu +24

Despite the more than one order of magnitude difference between the measured dipole moments in ${}^{144}$Ba and ${}^{146}$Ba, the strength of the octupole correlations in ${}^{146}$Ba ar…
