$\gamma$-soft ${}^{146}$Ba and the role of non-axial shapes at N ~ 90

A. J. Mitchell, C. J. Lister, E. A. McCutchan +29

Low-spin states in the neutron-rich, N = 90 nuclide ${}^{146}$Ba were populated following $\beta$-decay of ${}^{146}$Cs, with the goal of clarifying the development of deformation in Ba is…
